This program should return an array of two strings as output but NOT present in str2

Write a PHP program which takes two strings as input from the user (str1 and str2).<br>

This program should return an array of two strings as output (op1 and op2).<br>

op1 should contain all the characters which are present in str1 but NOT present in str2.<br>

op2 should contain all the characters which are present in str2 but NOT present in str1.

Example1:

Input1 : ABC

Input2 : BC

Outpt = A

Example2:

Input1 : BC

Input2 : BANGALORE

Outpt = C

Answer:

<?php

//BC BANGALORE = C

//ABC BC = A

//processStrings('BC','BANGALORE');

processStrings('ABC','BC');

function processStrings($str1, $str2) {

//echo strlen($str2);

$finalString = '';

for($i=0; $i<strlen($str1); $i++){

//echo "=".$str1[$i];

//Logic start

$jay1 = $str2;

$jay2 = $str1[$i];

if (strpos($jay1,$jay2) !== false) {

//echo "n $jay1 contains $jay2";

}else{

$finalString.=$jay2;

}

//logic close

}//for close

echo "n Result=".$finalString;

}
