7.6.6 searching and sorting slices and arraysThe standard library provides sort packages for common search and sorting operations. You can use the sort functions in the package func Ints(a []int) to sort the tiles of type int. For example

Package Main;import ("OS" "FMT" "StrConv") func main () {///Open file, return file pointer, error: = OS. Open ("./1.txt"); if error! = Nil {fmt. PRINTLN (error);} Fmt. Println (file); file. Close ();//Open file as read-write, if not present, create

First-get slice and string of memory dataFunc Stringpointer (S string) unsafe. Pointer {p: = (*reflect. Stringheader) (unsafe. Pointer (&s)) return unsafe. Pointer (P.data)}func bytepointer (b []byte) unsafe. Pointer {p: = (*reflect. Sliceheader)

the common internal sorting algorithms are: Insert Sort, hill sort, select sort, bubble sort, merge sort, quick sort, heap sort, cardinality sort and so on. Summarize with a picture:650) this.width=650; "Src="
