Write a program, which reads an array of integers from the console and receives commands, which manipulate the array. Your program may receive the following commands:
- Delete {element} – delete all elements in the array, which are equal to the given element
- Insert {element} {position} – insert element and the given position
You should stop the program when you receive the command Odd eller Even. If you receive Odd : print all odd numbers in the array separated with single whitespace, otherwise print the even numbers.

Here is my solution:
<?php
$arr = explode(" ", readline());
$input = readline();
while (true) {
$args = explode(" ", $input);
$command = $args[0];
if ($command == "Delete") {
$element = $args[1];
while (array_search($element, $arr) !== false) {
$index = array_search($element, $arr);
array_splice($arr, $index, 1);//remove
}
} else if ($command == "Insert") {
$element = $args[1];
$position = $args[2];
if ($position >= 0 && $position <= count($arr)) {
array_splice($arr, $position, 0, $element);//replace
}
}
if ($input == "Odd" || $input == "Even") {
$reminder = 0;
if ($input === "Odd") {
$reminder = 1;
}
for ($i = 0; $i < count($arr); $i++) {
if ($arr[$i] % 2 == $reminder) {
echo "$arr[$i] ";
}
}
echo PHP_EOL;
break;
}
$input = readline();
}
