Some might refer this to this as pseudo code being a common term in business software development where the clientside business object developers write pseudo code based on requirements.
An algorithm is a procedure for solving a problem in terms of the actions to be executed and the order in which those actions are to be executed. Some older texts and authors that were trained in such styles use. An algorithm is merely the sequence of steps taken to solve a problem. Pseudo codes are written with respect to programming language, but programming language syntax or grammar is not strictly followed. Additionally, transforming an algorithm presented in pseudocode to programming code could be much easier than converting an algorithm written in natural language. Once subarrays are sorted individually, the two subarrays are merged together to form a complete sorted array. Our our erp software xpedeon supports all pre and post contract activities from estimating to financial accounts.
