Summary

This PR implements a complete solution for issue #10 - generating all possible functions with 1-bit sized argument and implementing them using NAND gates.

What's Implemented

  • Complete Function Generation: Generates all 4 possible boolean functions for a single input:

    • F0: Constant 0 (always returns false)
    • F1: Identity (returns input value)
    • F2: NOT (returns negation of input)
    • F3: Constant 1 (always returns true)
  • NAND Gate Implementations: Each function is implemented using only NAND gates:

    • F0: ((x ↑ (x ↑ x)) ↑ (x ↑ (x ↑ x)))
    • F1: (x ↑ x) ↑ (x ↑ x)
    • F2: x ↑ x
    • F3: x ↑ (x ↑ x)
  • Truth Table Display: Shows complete truth table for all functions

  • Verification System: Tests each NAND implementation against expected outputs

  • Comprehensive Test Suite: Unit tests covering all functions and edge cases

Technical Details

The solution mathematically proves that these 4 functions represent the complete set of all possible boolean functions for a single input variable. Each NAND gate implementation is verified to produce the correct truth table.

Example Output

Truth table for all possible 1-bit functions:
Input | F0 | F1 | F2 | F3
------|----|----|----|----|
  0   | 0 | 0 | 1 | 1 |
  1   | 0 | 1 | 0 | 1 |

All implementations pass verification tests and demonstrate correct NAND gate logic.

Test Plan

  • All 4 function implementations verified against truth tables
  • NAND gate logic mathematically correct
  • Unit tests pass (6/6 tests passing)
  • Program compiles and runs successfully
  • Output matches expected format from CircuitVerse reference
