WebDec 1, 2024 · Given an array A [] with N integers, for each integer A [i] in the array, the task is to find the number of integers A [j] (j != i) in the array such that A [i] % A [j] = 0 or A [j] % A [i] = 0. Examples: Input: A = {2, 3, 4, 5, 6} Output: 2 1 1 0 2 Explanation: For i=0, the valid indices are 2 and 4 as 4%2 = 0 and 6%2 = 0. WebJul 30, 2024 · The ForLoop node gives you the choice of which index to start at and which to end at.
