The previously named "AlgoUnsupported" has been replaced with "AlgoCoinflip" in the algorithm tests in algo_test.go. Additionally, the "AlgoUnsupported" test has been moved down to keep the test sequence logical and comprehensive.
Test suite `TestIntToAlgo` was added to `algo_test.go` to validate `IntToAlgo` function. Additionally, Algorithm constants in `algo.go` have been prefixed with "Algo". These changes were made in order to make the code clearer and ensure the function returns the expected values for the given inputs.
