👉 "Pre-extract" is a term in computer science that refers to an algorithm or process where the output of one operation (such as addition, subtraction, multiplication, division) is used as input for another operation. This can be useful when you want to perform multiple operations on a single value and save space by not storing intermediate results. For example, consider the following algorithm: ``` int x = 5; int y = 3; x += y; // this adds y to x
