{ "data": { "question": { "questionId": "1755", "questionFrontendId": "1652", "boundTopicId": null, "title": "Defuse the Bomb", "titleSlug": "defuse-the-bomb", "content": "

You have a bomb to defuse, and your time is running out! Your informer will provide you with a circular array code of length of n and a key k.

\n\n

To decrypt the code, you must replace every number. All the numbers are replaced simultaneously.

\n\n\n\n

As code is circular, the next element of code[n-1] is code[0], and the previous element of code[0] is code[n-1].

\n\n

Given the circular array code and an integer key k, return the decrypted code to defuse the bomb!

\n

Example 1:

\n\n
\nInput: code = [5,7,1,4], k = 3\nOutput: [12,10,16,13]\nExplanation: Each number is replaced by the sum of the next 3 numbers. The decrypted code is [7+1+4, 1+4+5, 4+5+7, 5+7+1]. Notice that the numbers wrap around.\n
\n\n

Example 2:

\n\n
\nInput: code = [1,2,3,4], k = 0\nOutput: [0,0,0,0]\nExplanation: When k is zero, the numbers are replaced by 0. \n
\n\n

Example 3:

\n\n
\nInput: code = [2,4,9,3], k = -2\nOutput: [12,5,6,13]\nExplanation: The decrypted code is [3+9, 2+3, 4+2, 9+4]. Notice that the numbers wrap around again. If k is negative, the sum is of the previous numbers.\n
