PHP Exercises: Compute the sum of the two given arrays of integers, length 3 and find the array which has the largest sum

PHP Basic Algorithm: Exercise-99 with Solution

Write a PHP program to compute the sum of the two given arrays of integers, length 3 and find the array which has the largest sum.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes two arrays as parameters
function test($nums1, $nums2)
 { 
    // Compare the sum of the first three elements of $nums1 with the sum of the first three elements of $nums2
    // If the sum of $nums1 is greater or equal, return $nums1; otherwise, return $nums2
    return $nums1[0] + $nums1[1] + $nums1[2] >= $nums2[0] + $nums2[1] + $nums2[2] ? $nums1 : $nums2;
 }   

// Call the 'test' function with arrays [10, 20, -30] and [10, 20, 30] and store the result in $result
$result = test([10, 20, -30], [10, 20, 30]);

// Print the new array (either $nums1 or $nums2) with maximum values using 'implode' and 'echo'
echo "New array with maximum values: " . implode(',', $result);
?>

Explanation:

• Function Definition:
• A function named test is defined, which takes two arrays as parameters:
• $nums1: the first array of numbers.
• $nums2: the second array of numbers.
• Compare Sums of Elements:
• The function calculates the sum of the first three elements in each array:
• Sum of $nums1: $nums1[0] + $nums1[1] + $nums1[2].
• Sum of $nums2: $nums2[0] + $nums2[1] + $nums2[2].
• It then compares these sums:
• If the sum of $nums1 is greater than or equal to the sum of $nums2, the function returns $nums1.
• Otherwise, it returns $nums2.
• Test Case:
• The test function is called with two arrays: [10, 20, -30] and [10, 20, 30].
• The result is stored in $result.
• Display the Result:
• The resulting array (either $nums1 or $nums2) is printed.

Output:

New array with maximum values: 10,20,30

Previous: Write a PHP program to check a given array of integers, length 3 and create a new array. If there is a 5 in the given array immediately followed by a 7 then set 7 to 1.
Next: Write a PHP program to create an array taking two middle elements from a given array of integers of length even.
