Make The String Great - Given a string s of lower and upper case English letters. A shift on A consists of taking string A and moving the leftmost character to the rightmost position. More formally, if the value of the ith roll is equal to the value of the jth roll, then abs(i - j) > 2. However, she tends to be clumsy and may press a key for too long, resulting in a character being typed multiple times. You are given a string word Change a string.
