This is a collection of my HackerRank solutions written in Python3. The goal of this series is to keep the code as concise and efficient as possible. It might not be perfect due to the limitation of my ability and skill, so feel free to make suggestions if you spot something that can be improved.
Strings: Making Anagrams - Hacker Rank Solution. Two strings, and , will be anagrams of one another if they share all of the same characters and each character has the same frequency in both strings. Keep a count array for each string that stores the number of occurrences of each of character. Suppose character occurs times in string and times ...

May 29, 2017 · The idea behind this approach is to determine the starting index of the substring you are looking for. If you notice, I am performing a conditional check to determine if the result of the find method call is -1 or not. If the substring is not found, the find method will return -1. Meaning that the substring was not found in the parent string.
HackerRank - The Minion Game Solution. Kevin and Stuart want to play the ' The Minion Game '. Stuart has to make words starting with consonants. Kevin has to make words starting with vowels. The game ends when both players have made all possible substrings. Here, ANA occurs twice in BANANA. Hence, Kevin will get 2 Points.
Problem: Lilah has a string, s, of lowercase English letters that she repeated infinitely many times. Given an integer, n, find and print the number of letter a's in the first n letters of Lilah's infinite string. For example, if the string s = 'abcac' and n = 10, the substring we consider is , abcacabcac the first 10 characters of her infinite string.
Find the Longest Substring Containing Vowels in Even Counts in C++. Suppose we have the string s, we have to find the size of the longest substring containing each vowel an even number of times. That is, 'a', 'e', 'i', 'o', and 'u' must appear an even number of times. So if the string is like "helloworld", then the output will be 8.
Solution to CoderByte's "Vowel Count" Problem: Have the function VowelCount(str) take the str string parameter being passed and return the number of vowels the string contains (ie. "All cows eat grass" would return 5). Do not count y as a vowel for this challenge.
