https://codeforces.com/submissions/jimm89 For this user’s submission record, the code cannot be viewed on the first page, and the code can only be viewed from the second page. Is it a codeforces bug? upd: I took a screenshot to facilitate the codeforces staff to troubleshoot the cause when the bug cannot be reproduced. I guess the cause of the bug is probably related to the ongoing seven-day Kotlin practice contest.
