Contribute to RyanFehr/HackerRank development by creating an account on GitHub. All of the characters are the same, e.g. so if the string contains "a"s only simply return n. otherwise, count the number of a's in the string s, now using divmond() function I have found the number of string that can be added without surpassing n. for example string s is "aba" and n=10, so I can add 3 "abs"s completely without the length of string going over 10. now the number of a's in the added string (3*2). Arithmetic Operators – HackerRank Solution in Python. In one step, Alice can change a to a (or vice-versa). For every step he took, he noted if it was an uphill, U, or a downhill, D step.
