Bummer

I am replacing the elements individually but struggling. Any thoughts??

index.php 
<?php

$colors = array("Red","Green","Blue");
array_unshift($colors, 'Yellow');
array_push($colors, 'Black');
$colors[0]= 'Magenta';
$colors[2]= 'Cyan';
//add modifications below this line

Hi Shubham,

By adding "Yellow" to the beginning it shifts the existing colors forward by 1.

Initially, "Red" is at index 0.

But when you add "Yellow" to the beginning then that means that "Yellow" is now at index 0 and "Red" gets pushed forward to index 1
