Although we can use recursion to write the full array of programs, but since the STL already has this function why not directly use it, write a direct use of C + + STL to generate a fully sequenced programFunction Name: next_permutationInclude

First, the problem descriptionWrites multiple records to a file, with each record occupying one row. Each record is written to calculate the size ( in bytes ) and number of records of all records in the current file, and write to the first line of
