The page is a good start for people to solve these problems as the time constraints are rather forgiving. Problem Statement Objective. What is the fastest possible way to calculate all the possible substrings of a given string and check them for the following condition. It is also not done by double for-loops to add all possible strings to a set/list (less repeated ones), as that has to be done in O(n^2).

Explanation:-As we discuss above first calculate the size of both string, we can either use a size() function or loop for calculating the size of the string. Skip to content. Beeze Aal 17.Jul.2020. Ashton and String Hackerrank. We need to write a program that will print all non-empty substrings of that given string. We need to find all such possible substrings of a given very large string. Hacker Rank HackerRank in a String! Given a string as an input. Hackerrank - Special String Again Solution. So, I first convert the string to an array and then use index. This is not done by simple combinatorics (I know the formulas and it doesn't work here). Secondly, String.charAt() seems to be slower than accessing an array with an index. This challenge will help you learn the concept of recursion. Number of substrings of length two is n-1 (We can choose any of the n-1 pairs formed by adjacent) Number of substrings of length three is n-2 (We can choose any of the n-2 triplets formed by adjacent) In general, mumber of substrings of length k is n-k+1 where 1 <= k <= n; Total number of substrings of all lengths from 1 to n = n + (n-1) + (n-2) + (n-3) + … 2 + 1 = n * (n + 1)/2. Given a square matrix, calculate the absolute difference between the sums of its diagonals. This problem forced me to learn suffix tree. Could anyone help make my solution faster, please. If s is not a single char string but the s.length is smaller than n, simply use substring to get noOfA in a loop. Viewed 2k times 1. C/C++ Logic & Problem Solving i solve so many problem in my past days, programmers can get inspired by my solutions and find a new solution for the same problem. Description: Given a String s, a sub-string is defined as a non-empty string that can be obtained by applying following operation Remove zero or 1 character from left side of s Remove zero or 1 character from right side of s For example, ball < cat, dog < dorm, Happy < happy, Zoo < ball. how can i optimize this code , please help me.. int maxValue(string t) { Mental skills to help players; HackerRank - count string (V) - C plus plus solution; HackerRank: count string (IV) - JavaScript I'm trying to solve the String Function Calculation problem from Hackerrank.
