Challenge 13 - Smallest Difference between Ints

👋 Welcome Gophers! In this challenge, you are tasked with finding the smallest difference between two slices of int values.

Example: Let’s say I have 2 int arrays; [1, 2] and [4, 5]. The function should return the smallest difference which would be the difference between 2 and 4.

View Solution 
package main

import "fmt"

import "sort"

func CalcSmallestDifference(arr1, arr2 []int) int {  
  sort.Ints(arr1)
  sort.Ints(arr2)
  
  greater1 := arr1[len(arr1)-1]
  smaller2 := arr2[0]
  
  if (greater1 >= smaller2) {
return 0
  } 
  return smaller2 - greater1
}

func main() {
  fmt.Println("Smallest Difference Challenge")

  arr1 := []int{9, 8, 7, 6}
  arr2 := []int{7, 3, 2, 5}

  smallestDiff := CalcSmallestDifference(arr1, arr2)
  fmt.Println(smallestDiff)
}
