constitute a random combination of 1-99

// 生成1-100的数。然后随机打乱func rd_num() {sou_num := make([]int, 100)i := 0for k, _ := range sou_num {i++sou_num[k] = ifmt.Printf("%d[%d] ", sou_num[k], k)}fmt.Println("\n-----")for j := 0; j < 100; j++ {if j == 99 {break}x := random(j, 99)sou_num[x], sou_num[j] = sou_num[j], sou_num[x]fmt.Printf("%d ", sou_num[j])}fmt.Println("\n-----")}// 产生一个范围内随机数，原理：差值的随机数+最小值func random(min, max int) int {rand.Seed(time.Now().Unix())return rand.Intn(max-min) + min}
