Incremental Memory Leak — LeetCode 1860 Python Solution

The problem

You are given two integers memory1 and memory2 representing the available memory in bits on two memory sticks. There is currently a faulty program running that consumes an increasing amount of memory every second.

Example

Input

memory1 = 2, memory2 = 2

Output

[3,1,0]

Explanation

The memory is allocated as follows:

Python solution

class Solution:
    def memLeak(self, memory1: int, memory2: int) -> List[int]:
        i = 1
        while i <= max(memory1, memory2):
            if memory1 >= memory2:
                memory1 -= i
            else:
                memory2 -= i
            i += 1
        return [i, memory1, memory2]
