A peek at the ingenious combination of the depth-first search (DFS) algorithm and Java internal classes: solving the full permutation problem
1. Introduction: Solve this question in AcWing: 823. Arrangement In this question, an integer n is given, and the numbers 1 to n are required to be arranged in a row, and all arrangements are output in lexicographic order.

Verify the differences and uses of ByREF, ByVal, VarPtr, StrPtr, Poke, Peek, DBCS, SBCS, Ansi, and Unicode in VB6 programs
The string storage format affects programming usage. C format strings use \0 as the terminator, and their length can be calculated from this, while the length of VB format strings is stored in the string prefix. Not only that, the concepts of string encoding methods ansi, unicode, widestring, dbcs, sbcs also affect length calculation. Let’s […]
