Single-pass streaming algorithms terminate correctly for all inputs within LeetCode's stated constraints, because the deliberate contract of trusting input guarantees eliminates the edge cases that would cause divergence.
The no-validation contract and streaming patterns are mutually reinforcing — streaming works because inputs are trusted, and validation is skipped because streaming handles valid inputs correctly — but specific solutions break this contract by diverging on negative integers that Python's arbitrary-precision arithmetic never reduces to zero
