PHP Exercises: Check if it is possible to add two integers to get the third integer from three given integers

PHP Basic Algorithm: Exercise-46 with Solution

Write a PHP program to check if it is possible to add two integers to get the third integer from three given integers.

Sample Solution:

PHP Code :

<?php
// Define a function that checks if any two numbers add up to the third number
function test($x, $y, $z)
{
    // Check if $x is equal to the sum of $y and $z
    // OR if $y is equal to the sum of $x and $z
    // OR if $z is equal to the sum of $x and $y
    return $x == $y + $z || $y == $x + $z || $z == $x + $y;
}

// Test the function with different sets of numbers
var_dump(test(1, 2, 3))."\n";
var_dump(test(4, 5, 6))."\n";
var_dump(test(-1, 1, 0))."\n";
?>

Explanation:

• Function Definition:
• The function test checks if any two numbers from the inputs $x, $y, and $z add up to the third number.
• Conditions Checked:
• Condition 1: Checks if $x is equal to the sum of $y and $z.
• Condition 2: Checks if $y is equal to the sum of $x and $z.
• Condition 3: Checks if $z is equal to the sum of $x and $y.
• If any of these conditions are true, the function returns true; otherwise, it returns false.

Output:

bool(true)
bool(false)
bool(true)

Previous: Write a PHP program to check whether a given string starts with "F" or ends with "B". If the string starts with "F" return "Fizz" and return "Buzz" if it ends with "B" If the string starts with "F" and ends with "B" return "FizzBuzz". In other cases return the original string.
Next: Write a PHP program to check if y is greater than x, and z is greater than y from three given integers x,y,z.
