Hi Leetcode community, \n\nI tried to search for a similar post but couldn\'t find one so please either point me to a similar post or kindly provide your inputs here. \n\nI solved a [problem](https://leetcode.com/problems/reorder-data-in-log-files/solution/) on Leetcode and submitted my solution and the results mentioned that the runtime was 24 ms and that my solution was faster than ~17% of cpp submissions. \n\nNow, I tried submitting the solution again (same code no changes) within a few seconds of the above submission and I got a different results altogether. This time it mentioned that my solution took 12 ms ( half of before ) and was faster than ~81% \n\nI find it bizzare! Anyone else experienced the same or know why this might happen ? \n\nScreenshot attached for those of you who don\'t trust my eyes ( I didn\'t either, at first )\n\n![image](https://assets.leetcode.com/users/images/15c66925-f5bf-4cf5-a29a-ba0149e88404_1612386088.515.png)\n\n\nThanks in advance!
