World-writable file?

Challenge

Flag a world-writable file — a top finding in a permission audit, since any local user can tamper with it.

Task

Implement int audit_world_writable(int mode) that returns 1 if the other-write bit (octal 0002) is set, else 0.

Input

• mode: a Unix permission mode (octal). The grader passes fixed values.

Output

Returns int: 1 if the other-write bit is set, else 0.

Example

audit_world_writable(0777)   ->   1
audit_world_writable(0755)   ->   0

Edge cases

• Only the other-write bit matters; owner/group write bits are ignored.

Rules

• AND the mode with octal 0002.

Input format

A Unix permission mode (octal int).

Output format

An int: 1 if the other-write bit (0002) is set, else 0.

Constraints

Test mode & 0002.

Starter code

int audit_world_writable(int mode) {
    /* TODO */
    return 0;
}
