{ "data": { "question": { "questionId": "2465", "questionFrontendId": "2381", "boundTopicId": null, "title": "Shifting Letters II", "titleSlug": "shifting-letters-ii", "content": "

You are given a string s of lowercase English letters and a 2D integer array shifts where shifts[i] = [starti, endi, directioni]. For every i, shift the characters in s from the index starti to the index endi (inclusive) forward if directioni = 1, or shift the characters backward if directioni = 0.

\n\n

Shifting a character forward means replacing it with the next letter in the alphabet (wrapping around so that 'z' becomes 'a'). Similarly, shifting a character backward means replacing it with the previous letter in the alphabet (wrapping around so that 'a' becomes 'z').

\n\n

Return the final string after all such shifts to s are applied.

Example 1:

\n\n
\nInput: s = "abc", shifts = [[0,1,0],[1,2,1],[0,2,1]]\nOutput: "ace"\nExplanation: Firstly, shift the characters from index 0 to index 1 backward. Now s = "zac".\nSecondly, shift the characters from index 1 to index 2 forward. Now s = "zbd".\nFinally, shift the characters from index 0 to index 2 forward. Now s = "ace".
\n\n

Example 2:

\n\n
\nInput: s = "dztz", shifts = [[0,0,0],[1,1,1]]\nOutput: "catz"\nExplanation: Firstly, shift the characters from index 0 to index 0 backward. Now s = "cztz".\nFinally, shift the characters from index 1 to index 1 forward. Now s = "catz".\n
