Golang : Find smallest number in array




Alright, today I'll just write this simple tutorial on how to find the smallest value in an array. Basically, the algorithm is just iterate through the values inside the given array and replace the final value( which is the variable min) with the smallest value it can find.

Here's the code :

 package main

 import "fmt"

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

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

 for _, value := range arr {
 if value < min {
 min = value // found another smaller value, replace previous value in min
 }
 }

 fmt.Println("The smallest value is : ", min)
 }

Output :

The smallest value is : 5
