1652 - Defuse the Bomb\.

Easy

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.

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

• If k > 0, replace the <code>i^th</code> number with the sum of the next k numbers.

• If k < 0, replace the <code>i^th</code> number with the sum of the previous k numbers.

• If k == 0, replace the <code>i^th</code> number with 0.

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].

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

Example 1:

Input: code = 5,7,1,4, k = 3

Output: 12,10,16,13

Explanation: 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.

Example 2:

Input: code = 1,2,3,4, k = 0

Output: 0,0,0,0

Explanation: When k is zero, the numbers are replaced by 0.

Example 3:

Input: code = 2,4,9,3, k = -2

Output: 12,5,6,13

Explanation: 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.

Constraints:

• n == code.length

• 1 <= n <= 100

• 1 <= code[i] <= 100

• -(n - 1) <= k <= n - 1
