Revering Parts of Array: After we have calculated the value of K, reverse the first part of the array i.e. from 0 to N-K-1 and the second part from N-K to N-1 separately. Reverse the entire Array: Now, reverse the entire array i.e. from 0 to N-1. The array will be rotated according to the value of K.

WebDec 29, 2024 · The time complexity really depends on the unshift time complexity. ECMA does not specify it, but I would expect that it is not constant. I would not be surprised if it is actually linear in the size of the array. Pointer based approach: The base of this concept is the reversal algorithm for array rotation. The array is divided into two parts where the first part is of size (N-K) and the end part is of size K. These two parts are individually reversed. Then the whole array is reversed. Below is the implementation of the above approach: C++. Java. Python3. feeonly registered investment advisory firm https://waatick.com
