Given two numbers, display the process of finding the LCM, as in school.

Задание 2

Given an arbitrary two-dimensional array:

rust[
  [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],
}

Get the array of elements of its main diagonal:

rust[
  11, 22, 33, 44, 55
}
