LeetCode ProblemCan Convert String in K Moves
Given two strings s and t, your goal is to convert s into t in k moves or less. During the ith (1 <= i <= k) move you can: Shifting a character means replacing it by the next letter in the alphabet (wrapping around so that 'z' becomes 'a'). Shifting a character by i means applying the shift operations i times. Remember that any index j can be picked at most once. Return true if it's possible to convert s into t in no more than k moves, otherwise return false.
