Function rotateArray2DMinor

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

given a row-major (and column-minor) 2D array arr2d, this function would rotate its columns by the specified amount. a positive amount would rotate the columns 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, 16, 17, 18],
]
rotateArray2DMinor(arr2d, 2)
assertEquals(arr2d, [
	[5 , 6 , 1 , 2 , 3 , 4 ,],
	[11, 12, 7 , 8 , 9 , 10,],
	[17, 18, 13, 14, 15, 16,],
])
