/***************************************************************************************************** 
 *
 * 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.
 * 
 * At the i^th second (starting from 1), i bits of memory are allocated to the stick with more 
 * available memory (or from the first memory stick if both have the same available memory). If 
 * neither stick has at least i bits of available memory, the program crashes.
 * 
 * Return an array containing [crashTime, memory1crash, memory2crash], where crashTime is the time (in 
 * seconds) when the program crashed and memory1crash and memory2crash are the available bits of 
 * memory in the first and second sticks respectively.
 * 
 * Example 1:
 * 
 * Input: memory1 = 2, memory2 = 2
 * Output: [3,1,0]
 * Explanation: The memory is allocated as follows:
 * - At the 1^st second, 1 bit of memory is allocated to stick 1. The first stick now has 1 bit of 
 * available memory.
 * - At the 2^nd second, 2 bits of memory are allocated to stick 2. The second stick now has 0 bits of 
 * available memory.
 * - At the 3^rd second, the program crashes. The sticks have 1 and 0 bits available respectively.
 * 
 * Example 2:
 * 
 * Input: memory1 = 8, memory2 = 11
 * Output: [6,0,4]
 * Explanation: The memory is allocated as follows:
 * - At the 1^st second, 1 bit of memory is allocated to stick 2. The second stick now has 10 bit of 
 * available memory.
 * - At the 2^nd second, 2 bits of memory are allocated to stick 2. The second stick now has 8 bits of 
 * available memory.
 * - At the 3^rd second, 3 bits of memory are allocated to stick 1. The first stick now has 5 bits of 
 * available memory.
 * - At the 4^th second, 4 bits of memory are allocated to stick 2. The second stick now has 4 bits of 
 * available memory.
 * - At the 5^th second, 5 bits of memory are allocated to stick 1. The first stick now has 0 bits of 
 * available memory.
 * - At the 6^th second, the program crashes. The sticks have 0 and 4 bits available respectively.
 * 
 * Constraints:
 * 
 * 	0 <= memory1, memory2 <= 2^31 - 1
