Tell us what’s happening:

Please how can i calculate the arrays to get the required solution

Your code so far

// Example
var ourArray = [18,64,99];
ourArray[1] = 45; // ourArray now equals [18,45,99].

// Setup
var myArray = [18,64,99];

// Only change code below this line.

I suggest you solve first the other challenge, if you don’y know how to access the datas in an array you can’t modify them

is the example clear?

var ourArray = [50,40,30];
ourArray[0] = 15; // equals [15,40,30]
