When d>n example

Array.js

// let us have an array of n = 3 and d = 4
let samparr = [1,2,3];

// step 1 -> reverse d elements.
let samparr = ["out of bounds"]

// To resolve this we refactor d as d = d % n, 
// so d becomes 1 and 1<n so we rotate the array with d as 1.
let samparr = [1,2,3];

// step 2 -> reverse n-d elements.
let samparr = [1,3,2];

// step 3 -> reverse n elements. we get the rotated array.
let samparr = [2,3,1]
