How to Rotate an Array. e, the last element will be cyclically shifted to the starting position of @Jean: well, closures captures the whole scope chain; as long as the outer function is top-level, the impact should be negligible and it's O(1) anyway, whereas looking up the Array methods is Rotate the array to the right by k steps. For instance, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4]. Time Complexity: O(n), as we are visiting each element only twice. If all of the selected elements were moved to the right by one position, the array is said to be right rotated. Example 1 I tried to code a right rotation for a 2D array. Here is the main code: for (int k = 0; k < rotate; k++) { //rotate is the no of times to shift right for (int i = 0; i < n1; i++) { //n1 is On x86, this version inlines to a single rol r32, cl (or rol r32, imm8) with compilers that grok it, because the compiler knows that x86 rotate and shift instructions mask the shift What about just using pop(0)?.
