Problem Statement Jay has got an array A (1-based indexing) of N integers, and he wants to perform some shifting operations on the array. Each operation can be of 2 types. - [ 1 l r ] modify the array by removing all the elements till index l (i.e., the sub-array A[1..l-1] ) and place them after the element with index r.
