Bulk Shift Letters - Microsoft Top Interview Questions
You are given a lowercase alphabet string s and a list of integers shifts. Each element shifts[i] means to shift the first i + 1 letters of s by shifts[i] positions. Shifting a letter should wrap over "z" to "a". For example, shifting “z” by 2 results in “b”. Return the resulting string after applying shifts to s. Constraints 1 ≤ n ≤ 100,000 where n is the length of s and shifts Example 1 Input s = "afz" shifts = [1, 2, 1] Output "eia" Explanation We shif

You are given a list of integers nums of length n representing the current score of swimmers in a competition. There is one more round to swim and the first place winner for this round gets n points, second place n-1 points, etc. and the last place gets 1 point. Return the number of swimmers that can still win the competition after the last round. If you tie for first in points, this still counts as winning.
