Check Array Elements

Background

This problem involves checking specific conditions within a small integer array.

Problem Description

Given an integer array, return true if the array contains the number 2 exactly twice, or the number 3 exactly twice. The array will have a length of 0, 1, or 2.

Input Format

Input is given from standard input in the following format.

An array of integers, represented as space-separated numbers on a single line.

Output Format

Output is printed to standard output in the following format.

true or false

Sample

2 2

true

3 3

true

2 3

false

Sample Explanation

Sample 1: The array [2, 2] contains the number 2 exactly twice, so the output is true. Sample 2: The array [3, 3] contains the number 3 exactly twice, so the output is true. Sample 3: The array [2, 3] contains neither the number 2 twice nor the number 3 twice, so the output is false.

Constraints

Time limit: 1s, Memory limit: 1024KiB for each test case.
