Golang : Find biggest/largest number in array

Just a quick tutorial on how to find the biggest value in a given array. Nothing fancy, just a simple for loop to find the next biggest value in the array and replace the final value ( which is the variable max ) with the biggest value is can find.

Here's the code

 package main

 import "fmt"

 func main() {
 arr := []uint{
 28, 33, 16,
 7, 5, 88,

 max := arr[0] // assume first value is the smallest

 for _, value := range arr {
 if value > max {
 max = value // found another smaller value, replace previous value in max

 fmt.Println("The biggest/largest value is : ", max)

Output :

The biggest/largest value is : 88

Hope this simple tutorial can be useful to you. Cheers!
