Given a grid grid, a row index r and an integer k, return a new grid in which row r has
been slid k positions to the right, with values that fall off the end wrapping around to the
front. A negative k slides to the left. k may be larger than the row length. All other rows are
unchanged.
Examples
Input: grid = [[1, 2, 3, 4],
[5, 6, 7, 8]], r = 1, k = 1
Output: [[1, 2, 3, 4],
[8, 5, 6, 7]]
Input: grid = [[1, 2, 3, 4],
[5, 6, 7, 8]], r = 0, k = -1
Output: [[2, 3, 4, 1],
[5, 6, 7, 8]]
Constraints
1 <= rows, cols <= 100,0 <= r < rows,-10**6 <= k <= 10**6- The input grid must not be modified.
Goals
- Rotate a single row cyclically with a possibly negative or oversized shift
- Copy a grid while replacing exactly one row
