👉 In computer science, "preconcurrent" refers to a part of an algorithm that has not been executed yet. It is typically before any other parts of the algorithm have started executing. Preconcurrent operations can be useful in scenarios where the execution of one part of an algorithm may cause conflicts with another part. For example: ```python def add_numbers(a, b): return a + b # In this case, preconcurrent operations are not performed as they will result in a
