Write a Golang program to find the sum of digits for a given number
Examples
- num = 125 => 1 + 2 + 5 = 8
- num = 101 => 1 + 0 + 1 = 2
- num = 151 => 1 + 5 + 1 = 7
Approach to solve this problem
Step 1: Define a function that accepts numbers(num); type is int.
Step 2: Start a true loop until num becomes 0 and define res:=0.
Step 3: Find modulo and add to res.
Step 4: Divide num by 10.
Step 5: Return res.
Program
package main
import "fmt"
func findDigitSum(num int) int {
res := 0
for num>0 {
res += num % 10
num /= 10
}
return res
}
func main(){
fmt.Println(findDigitSum(168))
fmt.Println(findDigitSum(576))
fmt.Println(findDigitSum(12345))
}Output
15 18 15
