👉 Overchecking is a concept in mathematics and computer science where an algorithm or procedure is used to check if its input meets certain conditions before proceeding with execution. It's often used in error checking, data validation, and other systems that require pre-conditions for executing operations. In programming terms, it means performing a check at the beginning of each function call, method call, or loop iteration. This ensures that the program is only executed when necessary, preventing unnecessary computations that could lead to performance issues or crashes
