Given two positive integers A and B, find GCD of A and B.

**Example 1:**

**Input:** A = 3, B = 6
**Output:** 3
**Explanation:** GCD of 3 and 6 is 3

**Example 2:**

**Input:** A = 1, B = 1
**Output:** 1
**Explanation:** GCD of 1 and 1 is 1

**Your Task: **

You don't need to read input or print anything. Complete the function **gcd()** which takes two positive integers as input parameters and returns an integer.

**Expected Time Complexity:** O(log(min(A, B)))

**Expected Auxiliary Space: **O(1)

**Constraints:**

1 ≤ A, B ≤ 10^{9}
