How to check if a number has zero in the center in Go

Answer 1

package main

import (
	"fmt"
	"strconv"
)

func hasZeroInCenter(number int) bool {
	// Convert the number to a string
	numStr := strconv.Itoa(number)

	if len(numStr)%2 == 0 {
		return false // Even length = no center digit
	}

	centerIndex := len(numStr) / 2

	return numStr[centerIndex] == '0'
}

func main() {
	number := 3720961

	if hasZeroInCenter(number) {
		fmt.Println("yes")
