Its easy man i cant figure out the last test case though !!
1.Input an array of size n
2.Input number of rotations as r
3. r=r%n -> it reduces the number of repeatative rotations thus decreasing the complexity of our code . suppose the size of the array is 3 and number of rotations is also 3 then our loop wont run it will simply print the same elements .
take a temperory variable and store the leftmost element in it i.e a[o]
Now run the loop from 0 to second last element of the array
6.a[i]=a[i+1] -> shifts the element towards left for eg. for i=0 a[0]=a[1]; it shifts all the elements towards left
7.now simply store the first element in temp variable to the last position.
steps 4 to 7 for first rotation now while loop will run as per the given number of rotations these steps will be repeated until r becomes 0.
Left Rotation
