find the biggest and smallest number in the given slice or array using go lang

biggestandsmallest.go

package main

import "fmt"

func main() {
  var n, smallest, biggest int
  x := []int{
    48,96,86,68,
    57,82,63,70,
    37,34,83,27,
    19,97, 9,17,
  }

  for _,v:=range x {
    if v>n {
      fmt.Println(v,">",n)
      n = v
      biggest = n
    } else {
      fmt.Println(v,"<",n)
    }
  }

  fmt.Println("The biggest number is ", biggest)
  for _,v:=range x {
    if v>n {
      fmt.Println(v,">",n)
    } else {
      fmt.Println(v,"<",n)
      n = v
      smallest = n
    }
  }
  fmt.Println("The smallest number is ", smallest)
}

Pass in the Slice and it will return the biggest number in the slice.

func Biggest(seq []int) int {
	var cache int

	for i := 0; i < len(seq)-1; i++ {
		if seq[i] > seq[i+1] {
			if seq[i] > cache {
				cache = seq[i]
			}
		}

	}
	return cache
