    If the function is not inlined, then the additional overhead of the function calls will probably take longer to run (on the order of 10 processor instructions for most high-performance languages). Theoretically, this additional time to run could matter. Example of duplicate code fix via code replaced by the method

    One method for deduplicating data relies on the use of cryptographic hash functions to identify duplicate segments of data. If two different pieces of information generate the same hash value, this is known as a collision. The probability of a collision depends mainly on the hash length (see birthday attack).
