Hey Aayush, what the array_slice function takes the array you assign to it "$input" and takes a piece of it. It does this with the second value assigned , the offset, which determines how far form the start (positive value) or the end (negative value). The next value is the length of the sequence, a.k.a. how many of the numbers it will include, so in this case, your array is $input, your offset is -2, and your length is 1, so your starting 2 from the end and only including 1 number "d". Lengthy answer I know but I hope this helps!
