Given four integers ‘a’, ‘b’, ‘y’ and ‘x’, where ‘x’ can only be either zero or one. Your task is as follows:
- If ‘x’ is zero assign value ‘a’ to the variable ‘y’
- If ‘x’ is one assign value ‘b’ to the variable ‘y’.
It is not allowed to use any conditional operator (including the ternary operator).
Examples :
Input : a = 3, b = 7, x = 1
Output : y = 7
Input : a = 3, b = 7, x = 0
Output : y = 3
The idea is to create an array of size two where the first element is ‘a’ and the second element is ‘b’. We use x as an index in the array.
C++
#include <iostream>
using namespace std;
int assignValue(int a, int b, bool x)
{
int arr[] = {a, b};
return(arr[x]);
}
int main()
{
int y = assignValue(3, 7, 0);
cout << y;
return 0;
}

Java
class GFG {
static int assignValue(int a, int b, int x)
{
int arr[] = {a, b};
return (arr[x]);
}
public static void main(String[] args)
{
int y = assignValue(3, 7, 0);
System.out.println(y);
}
}
|
Python3
def assignValue(a, b, x):
arr = [a, b]
return(arr[x])
y = assignValue(3, 7, 0)
print(y)
|
C#
using System;
public class GFG {
static int assignValue(int a, int b, int x)
{
int []arr = {a, b};
return (arr[x]);
}
public static void Main()
{
int y = assignValue(3, 7, 0);
Console.WriteLine(y);
}
}

PHP
<?php
function assignValue($a, $b, $x)
{
$arr = array($a, $b);
return($arr[$x]);
}
$y = assignValue(3, 7, 0);
echo $y;
?>

Javascript
<script>
function assignValue(a , b , x) {
var arr = [ a, b ];
return (arr[x]);
}
var y = assignValue(3, 7, 0);
document.write(y);
</script>
|
Output :
3
Alternate Solution :
C++
#include <iostream>
using namespace std;
int assignValue(int a, int b, bool x)
{
return (1 - x)*a + x*b;
}
int main()
{
int y = assignValue(3, 7, 0);
cout << y;
return 0;
}
|
Java
import java.io.*;
class GFG {
static int assignValue(int a, int b, int x)
{
return (1 - x) * a + x * b;
}
public static void main (String[] args)
{
int y = assignValue(3, 7, 0);
System.out.println(y);
}
}
|
Python3
def assignValue(a, b, x):
return (1 - x) * a + x * b
y = assignValue(3, 7, 0)
print(y)
|
C#
using System;
class GFG {
static int assignValue(int a, int b, int x)
{
return (1 - x) * a + x * b;
}
public static void Main()
{
int y = assignValue(3, 7, 0);
Console.WriteLine(y);
}
}
|
Javascript
<script>
function assignValue(a , b , x) {
return (1 - x) * a + x * b;
}
var y = assignValue(3, 7, 0);
document.write(y);
</script>
|
Output :
3
Time Complexity: O(1)
