Pointers

Pointer dereference

Report a typo

Obtain the value from the ptr pointer, assign it to the num variable, and finally return the value of num.

Write a program in Go

package main

import "fmt"

func solve(ptr *int) int {

var ? = ? // assign the value of the pointer 'ptr' to the variable 'num'

return ? // return the value of the variable 'num'

}

// DO NOT change the contents of the main function!

func main() {

var num = new(int)

fmt.Scan(num)

var test = solve(num)

fmt.Println(test)

}
