Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers.If Such arrangement is not a possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order).The replacement must is in-place, do not allocate extra memory.Here is some examples. Inputs is in the left-hand column and its corresponding outputs is in the right-hand column.1,2,3→1,3,23,2,1→1,2,31,1,5→1,5,1Test instructions: Sort the existing numbers to find

Things to do yesterday:The use of TXT to achieve the account password to save.The difficulties encountered:When you read the data in TXT, you can't pinpoint the value of a row, and it's inconvenient to read when there are many variables stored. And I see the config file in the game, there are a lot of lines, so there should be a better way.Things to do today:The table does not refresh when the bug,bug in the table is a second click Query.The first day of the second stage of the sprint, May

Title DescriptionEvery year children's Day, Nowcoder will prepare some small gifts to visit the orphanage children, this year is also the case. HF as the senior veteran of the Nowcoder, naturally also prepared some small games. Among them, there is a game like this: first, let the children surround a big circle. Then, he randomly assigned a number m, so that the number of children numbered 0 began to count. Every time the child shouted to M to sing a song, and then can be in the Gift box arbitra
