How to use ?

1. Create an instance (object) by either of the following ways :

1.1 Without providing any initial value -

    bigint b;
    cout<<b<<"\n";

1.2. With a long long int -

used the same logic described here.I wonder why there is so much diffrence when array of fixed size is used instead of unordered_map. Also, why the later solution gives TLE as well.

academic_records_management

A C-program for academic records management.

What does it do ? 🤔❓

It stores academic records of students, instructors and courses in a college.

How is it implemented ? 🤷‍♂️

The ideas used are :
- structure
- pointers

	for each index, dp[0][i] stores length of longest increasing sequence starting at index i, and dp[1][i] stores length
