Understanding the Shifting Letters Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a string s of lowercase English letters and an integer array shifts of the same length. Call the shift() of a letter, the next letter in the alphabet, (wrapping around so that 'z' becomes 'a'). For example, shift('a') = 'b', shift('t') = 'u', and shift('z') = 'a'. Now for each shifts[i] = x, we want to shift the first i + 1 letters of s, x times. Return the final string after all such shifts to s are applied.

Examples
s = "abc", shifts = [3,5,9]"rpl"We start with "abc". After shifting the first 1 letters of s by 3, we have "dbc". After shifting the first 2 letters of s by 5, we have "igc". After shifting the first 3 letters of s by 9, we have "rpl", the answer.
s = "aaa", shifts = [1,2,3]"gfd"Constraints
1 <= s.length <= 105s consists of lowercase English letters.shifts.length == s.length0 <= shifts[i] <= 109How Interview Coder Helps with Leetcode Problems
