Answer to Question #288888 in C for bharath

Question

Taru exam is on the head. So she started learning physics. There she learned about Pascal's law. Now she wanted to try an experiment to get a better understanding of the same.

For, the experiment Taru has N buckets (numbered from 1,2,3...N) which all are initially empty.

She has M number of queries. Each query represents an integer that is of 4 types.

• Query 1: Fill all the buckets with water.
• Query 2: Empty all even valued buckets (2, 4, 6 ... N).
• Query 3: Empty all odd number buckets (1, 3, 5, ... N).
• Query 4: Empty all the buckets. (1,2,3...N).

You have to return the number of buckets that are filled after performing M queries.

    All  1


    For the experiment Taru has N buckets (numbered from 1,2,3...N) which all are initially empty.
    She has M number of queries. Each query represents an integer that is of 4 types.
    Query 1: Fill all the buckets with water.
    Query 2: Empty all even valued buckets (2, 4, 6 (N).
    Query 3: Empty all odd number buckets (1, 3, 5,
    Query 4: Empty all the buckets. (1,2,3...N).


    You have to return the number of buckets that are filled after performing M queries.
