👉 Presubstituting, also known as "substitution," is a process in computer programming where a new value is assigned to a variable before it has been used for its intended purpose. This practice can be useful in several scenarios:
1.
Improvement of Performance:
Presubstituting allows for more efficient code by avoiding unnecessary checks and data structures, which can often lead to better performance.
2.
Code Reusability:
By replacing existing values with new ones before use, it makes
