WebAug 20, 2024 · Let us first think about what we need to perform the required task of rotating the list counter-clockwise by X nodes. For linked list rotation, we have to change the next of X th node to NULL, next of the last node to the head node, and finally, make the head point to the (X+1) th node. So, we need X th node, (X+1) th node and the last node.

Hashing by cyclic polynomial —sometimes called Buzhash—is also simple, but it has the benefit of avoiding multiplications, using barrel shifts instead. It is a form of tabulation hashing: it presumes that there is some hash function from characters to integers in the interval . This hash function might be simply an array or a hash table mapping characters to random integers. Let the function be a cyclic binary rotation (or circular shift): it rotates the bits by 1 to the left, pushing th…
