Problem Description

Bitwise Operators: Permission Flag Management

Learning Objective: Set and check flags using bitwise operators (&, |, ^)

Create a user permission system. Use bitwise operators to manage read, write, and execute permissions.

Permission Flags

READ = 1 (binary: 001)
WRITE = 2 (binary: 010)
EXECUTE = 4 (binary: 100)

Input

Line 1: Current permission value (integer 0-7)
Line 2: Permission to check (1=READ, 2=WRITE, 4=EXECUTE)

Output

Permission: [current permission]
[permission name]: [yes/no]
