A & B & C by CodeChum Solution - AskTheCode

C++ program to find A & B & C | CodeChum Solution | C++ Programming

Problem:

I am the creator of the Truth Machine! It’s a machine that accepts 3 numbers, with each number having an accompanying bit position (since the numbers are going to be in binary). After successfully getting 1 bit from each number, the machine would then process the numbers to give us either a 1 or 0, depending on how truthful the bits processed are. I feel like no one in the world could possibly make something like it again!

Care to prove me wrong?

Input Format:

A single line containing six values: x1, x2, y1, y2, z1, and z2.

x1 represents A.

x2 represents bit position of A (starting 0 from right to left).

y1 represents B.

y2 represents bit position of B (starting 0 from right to left).

z1 represents C.

z2 represents bit position of C (starting 0 from right to left).

Output Format:

A single line containing either a 1 or 0.

Input Sample:

3 1 5 1 3 1

Output Sample:

0
