Problem Brief

Minimum Extra Chocolates

OA

Given two boxes of chocolate containing A and B chocolates representing the number of chocolates Alex and Drake have, respectively. Drake is the younger child and will only be happy if he receives a multiple of what Alex gets. You decided to buy some extra chocolates.

Mathematically, The share of chocolates will be: k * (A + X) = (B + Y) for some non-negative integer X and Y and some positive integer k.

What is the minimum number of extra chocolates (X + Y) that you need to buy?

Note: The original chocolates (A and B) cannot be transferred among each other.

Function Description

Complete the function solution. The function takes 2 parameters and returns the solution:

  • A: Represents the number of initial chocolates in Alex's box
  • B: Represents the number of initial chocolates in Drake's box

1Example 1

Input
A = 8, B = 16
Output
0
Explanation

For the given test case, if you let X=0 and Y=0, then B+Y=16 will be a multiple of A+X=8. Here, you have X+Y=0, and there is no way to make X+Y smaller, so the answer is 0.

2Example 2

Input
A = 7, B = 37
Output
4
Explanation

Adding 1 to A and 3 to B, we get A as 8 and B as 40, which satisfies the condition as k*A=B. k will be 5 here.

3Example 3

Input
A = 70, B = 229
Output
9
Explanation

X will be 7 and Y will 2, k will end up becoming 3.
