The Divide and Conquer algorithm consists of a dispute using the three steps listed below.

Divide the original problem into sub-problems.

Conquer: Solve each sub-problem one at a time, recursively.

Combine: Put the solutions to the sub-problems together to get the solution to the whole problem.

Hashing is a technique or process that uses a hash function to map keys and values into a hash table. It is done to allow for quicker access to elements. The efficiency of mapping is determined by the hash function’s efficiency.
