{ "data": { "question": { "questionId": "1971", "questionFrontendId": "1860", "categoryTitle": "Algorithms", "boundTopicId": 772198, "title": "Incremental Memory Leak", "titleSlug": "incremental-memory-leak", "content": "
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 ith
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.
\n
Example 1:
\n\n\nInput: memory1 = 2, memory2 = 2\nOutput: [3,1,0]\nExplanation: The memory is allocated as follows:\n- At the 1st second, 1 bit of memory is allocated to stick 1. The first stick now has 1 bit of available memory.\n- At the 2nd second, 2 bits of memory are allocated to stick 2. The second stick now has 0 bits of available memory.\n- At the 3rd second, the program crashes. The sticks have 1 and 0 bits available respectively.\n\n\n
Example 2:
\n\n\nInput: memory1 = 8, memory2 = 11\nOutput: [6,0,4]\nExplanation: The memory is allocated as follows:\n- At the 1st second, 1 bit of memory is allocated to stick 2. The second stick now has 10 bit of available memory.\n- At the 2nd second, 2 bits of memory are allocated to stick 2. The second stick now has 8 bits of available memory.\n- At the 3rd second, 3 bits of memory are allocated to stick 1. The first stick now has 5 bits of available memory.\n- At the 4th second, 4 bits of memory are allocated to stick 2. The second stick now has 4 bits of available memory.\n- At the 5th second, 5 bits of memory are allocated to stick 1. The first stick now has 0 bits of available memory.\n- At the 6th second, the program crashes. The sticks have 0 and 4 bits available respectively.\n\n\n
\n
Constraints:
\n\n0 <= memory1, memory2 <= 231 - 1
给你两个整数 memory1
和 memory2
分别表示两个内存条剩余可用内存的位数。现在有一个程序每秒递增的速度消耗着内存。
在第 i
秒(秒数从 1 开始),有 i
位内存被分配到 剩余内存较多 的内存条(如果两者一样多,则分配到第一个内存条)。如果两者剩余内存都不足 i
位,那么程序将 意外退出 。
请你返回一个数组,包含 [crashTime, memory1crash, memory2crash]
,其中 crashTime
是程序意外退出的时间(单位为秒), memory1crash
和 memory2crash
分别是两个内存条最后剩余内存的位数。
\n\n
示例 1:
\n\n输入:memory1 = 2, memory2 = 2\n输出:[3,1,0]\n解释:内存分配如下:\n- 第 1 秒,内存条 1 被占用 1 位内存。内存条 1 现在有 1 位剩余可用内存。\n- 第 2 秒,内存条 2 被占用 2 位内存。内存条 2 现在有 0 位剩余可用内存。\n- 第 3 秒,程序意外退出,两个内存条分别有 1 位和 0 位剩余可用内存。\n\n\n
示例 2:
\n\n输入:memory1 = 8, memory2 = 11\n输出:[6,0,4]\n解释:内存分配如下:\n- 第 1 秒,内存条 2 被占用 1 位内存,内存条 2 现在有 10 位剩余可用内存。\n- 第 2 秒,内存条 2 被占用 2 位内存,内存条 2 现在有 8 位剩余可用内存。\n- 第 3 秒,内存条 1 被占用 3 位内存,内存条 1 现在有 5 位剩余可用内存。\n- 第 4 秒,内存条 2 被占用 4 位内存,内存条 2 现在有 4 位剩余可用内存。\n- 第 5 秒,内存条 1 被占用 5 位内存,内存条 1 现在有 0 位剩余可用内存。\n- 第 6 秒,程序意外退出,两个内存条分别有 0 位和 4 位剩余可用内存。\n\n\n
