New cell-scale robots can sense their environment, compute decisions, and move independently without magnetic or ultrasonic control systems.

The rotate function was initially not implemented, causing the program to fail when attempting to rotate the array by k steps to the right. As a result, the expected rotated output was not being ...

An array is not useful in places where we have operations like insert in the middle, delete from the middle, and search in unsorted data. If you only search occasionally: Linear search in an array or ...
