Rust Taskbook Level 10.7

Given two numbers, display the process of dividing these numbers in a column, as in school.

Given an arbitrary two-dimensional array:

[
	[11, 12, 13, 14, 15],
	[21, 22, 23, 24, 25],
	[31, 32, 33, 34, 35],
	[41, 42, 43, 44, 45],
	[51, 52, 53, 54, 55],
}

Zero out the elements that are not on the diagonals:

[
	[11,  0,  0,  0, 15],
	[ 0, 22,  0, 24,  0],
	[ 0,  0, 33,  0,  0],
	[ 0, 42,  0, 44,  0],
	[51,  0,  0,  0, 55],
}

Given an arbitrary two-dimensional array:

[
	[11, 12, 13, 14, 15],
	[21, 22, 23, 24, 25],
	[31, 32, 33, 34, 35],
	[41, 42, 43, 44, 45],
	[51, 52, 53, 54, 55],
}

Write code that will get an array of values for a given column:

[
	13, 23, 33, 43, 54
}
