It's guaranteed that this value is at least 32767." On the Codeforces machines, it turns out RAND_MAX is exactly 32767. That's so small! It doesn't stop there though; random_shuffle() also uses rand(). Recall that in order to perform a random shuffle, we need to generate random indices up to n, the size of the array.
Input. The first line contains a single integer t t (1 ≤ t ≤ 1440 1 ≤ t ≤ 1440) — the number of test cases. The only line of each test case contains a string s s of length 5 5 with format hh:mm representing a valid time in the 24-hour format. hh represents the hour from 00 00 to 23 23, and mm represents the minute from 00 00 to 59 59 ...

26 paź 2021 · So on the Codeforces platform, the AVX2 pragmas may be potentially not very neighbour-friendly among other things. Imagine a quadcore judge machine, which processes 4 submissions in parallel. If 3 of them are actively using AVX2, then it's possible that the CPU may downclock and affect the performance of the unsuspecting 4th non-AVX2 submission too.
2 seconds. memory limit per test. 256 megabytes. When Valera has got some free time, he goes to the library to read some books. Today he's got t free minutes to read. That's why Valera took n books in the library and for each book he estimated the time he is going to need to read it. Let's number the books by integers from 1 to n.
