Sign in . So if S = “heyfriendshowareyou” and K is 5, then output will be 15, as the strings are [heyfr, eyfri, yfrie, frien, riend, iends, endsh, ndsho, dshow, showa, howar, oware, warey, areyo, reyou] Example 2: Input: jaja Ouput: 7 Explanation Long repeated substring. Here are the steps to how it's done, Create a list of vowels for reference and assign [ a, e, i, o, u ]. Example 1: Print all substrings of a given string; Sum of all sub arrays in O(n) Time; Print all middle elements of the given matrix/2D array. This particular task can also be performed using the inbuilt function of combinations, which helps to get all K length the possible combinations i.e the substrings from a string. Above solution is of o(n^3) time complexity. Calculate the total number of unique substrings of the given string. After having such function, you can binary search over the length of the palindrome, this is: fix a length k, then go over every substring of length k and check whether it is or not a palindrome. If such a substring exists then print YES else print NO. Given a text string and an integer k, find the longest substring that is repeated k or more times. Here string BCG has ASCII sum 300, ABC has ASCII sum 294, both are divisible by k = 3. Writing code in comment? Longest substring with at most K unique characters; Find Factorial of a given Number; Print all steps to convert one string to another string; Insert a node in the given sorted linked list. Examples: Input : s = "aabbcc" k = 2 Output : 6 The substrings are aa, bb, cc, aabb, bbcc and aabbcc. If so, check to make sure you didn't get unlucky.

Longest k-repeated substring. Given a string str. Input : s = "aabccc" k = 2 Output : 3 There are three substrings aa, cc and cc Output : The original string is : Geeks All K length substrings of string are : ['Gee', 'eek', 'eks'] Attention geek! Experience. brightness_4 Generate all the strings of length n from 0 to k-1. Counting this later part comes down to our original problem: getting the "Number of strings (of length n) containing a specific substring" only for a smaller length (now the length of our prefix, instead of the length of the entire string). 1. class Solution {2. public: 3 Print all middle elements of the given matrix/2D array. Example 1: Input: ... We need only to check all sub-strings of length k. Show Hint 2. Sum of all Subarrays | Set 1; Find subarray with given sum | Set 1 (Nonnegative Numbers) Find subarray with given sum | Set 2 (Handles Negative Numbers) Find subarray with given sum with negatives allowed in constant space; Smallest subarray with sum greater than a given value; Find maximum average subarray of k length For k = 3, o/p is ‘bcbdbdbbdcd’ For k = 5, o/p is ‘abcbdbdbbdcdabd’ A simple solution would be to generate all substrings of the given string and return the longest substring containing k distinct characters. 2a) What we can do here is count all possibilities of filling in the prefix and then subtract the possibilities where s is in. The 6 unique substrings are {a, b, d, ab, bd, abd}. Attention geek! Method 2 In this method the main idea is to use hash table Time Complexity : O (n*n) String currStr = s.substring (0, k); String lexMin = currStr; String lexMax = currStr; for (int i = k; i < s.length (); i++) {. Find all possible substrings after deleting k characters in Python Python Server Side Programming Programming we are given a string. Social Network Problem; Print all subarrays using recursion; Count and print all Subarrays with product less than K in O(n) Find all unique combinations of numbers (from 1 to 9 ) with sum to N Each candy costs 1 unit. Compare every vowel count of substrings and return the maximum vowel count. This is the best place to expand your knowledge and get prepared for your next interview. I like this problem, so i decided to put my solution on my site.Below is the question and solution… Read More » And the value of k is 3. By using our site, you The combination of list comprehension and string slicing can be used to perform this particular task. Level up your coding skills and quickly land a job. Generate all possible substrings and check whether the substring has exactly k distinct characters or not. The approach is simple. Viewed 1k times 2 \$\begingroup\$ Here is the problem I'm working on (Satan's apple with bounded memory decision problem): Suppose I offer you slices of an apple, first \$1/2\$, then \$1/4\$, ... then \$1/2^k\$, etc. First line input: a string s. Second line input: an integer denoting k.; The Format of Output: The respective lexicographically the smallest and the largest substrings of the string s as a single newline-separated string. Matching substrings within two strings. Please go through Frequently asked java interview Programs for more such programs. Hash each substring of length L, and check if any hash occurs K or more times. I would say to use a suffix array instead, but if you already have a suffix tree, building a suffix array from a suffix tree takes linear time by DFS. To address this just run two binary search, first over … Since you don't know L, repeatedly double your guess of L until you know the … Strengthen your foundations with the Python Programming Foundation Course and learn the basics. C++. One solution. The complexity of this solution would be O(n 3).. We can solve this problem in O(n 2) time and O(1) space. Given an array, Print sum of all subsets; Given an array, print all unique subsets with a given sum. Given a string and an integer k, find number of substrings in which all the different characters occurs exactly k times. String k = "ALGO" N=2 Result: AA LA GA OA AL LL GL OL AG LG GG OG AO LO GO OO Approach: This problem is quite similar to Print All N Length Strings from Given Number K. Loop through i = 1 to K. Add k[i] to the result Array, which is the size N and make a recursive call to (N-1). The number of distinct sub-strings should be exactly 2^k. Example 1: Input: abd Ouput: 6 Explanation: str = abd. Transactional partially … Binary string that contains all substrings of length k exactly once. Input: str = google Output: e l g o oo goog A simple solution would be to generate all substrings of the given string and print substrings that are palindrome. res = [test_str [x:y] for x, y in combinations (range(len(test_str) + 1), r = 2) if len(test_str [x:y]) == K ] print("All K length substrings of string are : " + str(res)) chevron_right. generate link and share the link here. Pick One. currStr = currStr.substring (1, k) + s.charAt (i); if (lexMax.compareTo (currStr) < 0) lexMax = currStr; if (lexMin.compareTo (currStr) > 0) lexMin = currStr; Print maximum occurring character in a String; Given an array, find three-element sum closest to Zero; Check if one string is a subsequence of another string. This particular utility is very popular in competitive programming and having shorthands to solve this problems can always be handy. edit Base case: when n becomes 0 (means array is full). Input The first line contains a single integer T, the number of test cases. Ask Question Asked 5 years, 7 months ago. Longest common substring among three strings. So if S = “heyfriendshowareyou” and K is 5, then output will be 15, as the strings are [heyfr, eyfri, yfrie, frien, riend, iends, endsh, ndsho, dshow, showa, howar, oware, warey, areyo, reyou], To solve this, we will follow these steps −, Let us see the following implementation to get a better understanding −, Find all possible substrings after deleting k characters in Python, Maximum count of substrings of length K consisting of same characters in C++, Find number of substrings of length k whose sum of ASCII value of characters is divisible by k in C++, Count number of substrings with exactly k distinct characters in C++, Program to find length of longest substring which contains k distinct characters in Python, Program to find length of substring with consecutive common characters in Python, Find the longest substring with k unique characters in a given string in Python, Program to find k-length paths on a binary tree in Python, Count substrings with same first and last characters in C++.
