Add missimg searching algorithms in searching folder

[Adityakumar37]

We currently have a directory dedicated to searching algorithms, but it is missing implementations for several fundamental algorithms that would make the collection more comprehensive and useful for educational and practical purposes.

Goal: Implement the missing searching algorithms in the searching/ directory.

Missing Algorithms to Implement:
Jump Search

Interpolation Search

Exponential Search

Fibonacci Search
