Hi Guyz,
In this video, we will see how to left rotate the array in java.

Algorithm :
1) Take the input array and noOfRotations (input for the number of times the array is to be rotated)
2) Take a variable rotating point = noOfRotations
3) Iterate a while loop from rotating point up to the size of the array
4) Take an output array with index i initialized to 0
5) Copy elements from input array[rotatingIndex] to the output array[i]
6) Increment rotating point and index i
7) Set rotating point back to 0
8) Iterate a while loop from rotating point up to noOfRotations
9) Copy elements from input array[rotatingIndex] to the output array[i]
10) Increment rotating point and index i
