Today, my friend asked me a question: Requirement: generate 0 ~ 9. The number is 10 and cannot be repeated within 10 times. I gave his answer without thinking about it at the time: ----------------------------------------------------- # Include # Include Using namespace STD; Int main () { Srand (time (0 )); Int n = rand () % 10; For (INT I =

Compress the n-base array into a string (0-9 a-z) and decompress it. There are two points to define such a question: 1. Create a table: index the character with an array subscript. Note that if the character is returned to a number: Int index = (str [I]> = '0' str [I] 2. Pay attention to whether the low position is in front of the high position. If the first po
