# ChatGPT coding challenge 2022.12.11 – complete game of Math24

“Write a GoLang program that can play the game of Math 24 and if the players gets the wrong answer, provide the answer.”

ChatGPT Answer (limitation, not able to validate anything more than simple addition)

``````package main

import (
"bufio"
"fmt"
"math/rand"
"os"
"strconv"
"strings"
"time"
)

func main() {
// Generate 4 random numbers between 1 and 10
rand.Seed(time.Now().UnixNano())
n1 := rand.Intn(10) + 1
n2 := rand.Intn(10) + 1
n3 := rand.Intn(10) + 1
n4 := rand.Intn(10) + 1

// Make sure the numbers can be used to solve the equation 24 using only addition and multiplication
for n1+n2+n3+n4 != 24 && (n1*n2 != 24 && n1*n3 != 24 && n1*n4 != 24 && n2*n3 != 24 && n2*n4 != 24 && n3*n4 != 24) {
n1 = rand.Intn(10) + 1
n2 = rand.Intn(10) + 1
n3 = rand.Intn(10) + 1
n4 = rand.Intn(10) + 1
}

// Ask the player to solve the equation 24 using the 4 numbers
fmt.Printf("Solve the equation 24 using the numbers %d, %d, %d, and %d\n", n1, n2, n3, n4)
