TASK #1 › Common Factors

Submitted by: Niels van Dijke

You are given 2 positive numbers $M and $N.

Write a script to list all common factors of the given numbers.

Example 1:

Input:
    $M = 12
    $N = 18

Output:
    (1, 2, 3, 6)

Explanation:
    Factors of 12: 1, 2, 3, 4, 6
    Factors of 18: 1, 2, 3, 6, 9

Example 2:

Input:
    $M = 18
    $N = 23

Output:
    (1)

Explanation:
    Factors of 18: 1, 2, 3, 6, 9
    Factors of 23: 1

TASK #2 › Interleave String

Submitted by: Mohammad S Anwar

You are given 3 strings; $A, $B and $C.

Write a script to check if $C is created by interleave $A and $B.

Print 1 if check is success otherwise 0.

Example 1:

Input:
    $A = "XY"
    $B = "X"
    $C = "XXY"

Output: 1

EXPLANATION

"X" (from $B) + "XY" (from $A) = $C

Example 2:

Input:
    $A = "XXY"
    $B = "XXZ"
    $C = "XXXXZY"

Output: 1

EXPLANATION

"XX" (from $A) + "XXZ" (from $B) + "Y" (from $A) = $C

Example 3:

Input:
    $A = "YX"
    $B = "X"
    $C = "XXY"

Output: 0
