Added new question on greedy algorithm concept

[kondekarshubham123]

Describe your change:

Added my solution on for below question

Question:
There is one meeting room in a firm. There are N meetings in the form
of (start[i], end[i]) where start[i] is start time of meeting i and end[i]
is finish time of meeting i.
What is the maximum number of meetings that can be accommodated in the
meeting room when only one meeting can be held in the meeting room at a particular time?

Note: Start time of one chosen meeting can't be equal to the end time of
the other chosen meeting.
