Function rotateArray2DMajor

mutate and rotate the major-axis of a 2D array by the specified amount to the right.

given a row-major 2D array arr2d, this function would rotate its rows by the specified amount. a positive amount would rotate the rows to the right, and a negative amount would rotate it to the left.

Example

import { assertEquals } from "jsr:@std/assert"

const arr2d: Array2DRowMajor<number> = [
	[1 , 2 , 3 ],
	[4 , 5 , 6 ],
	[7 , 8 , 9 ],
	[10, 11, 12],
	[13, 14, 15],
]
rotateArray2DMajor(arr2d, 2)
assertEquals(arr2d, [
	[10, 11, 12],
	[13, 14, 15],
	[1 , 2 , 3 ],
	[4 , 5 , 6 ],
	[7 , 8 , 9 ],
