👉 Counteradvance is a mechanism used in computer science, particularly in the context of algorithm design and analysis. It involves decrementing the value stored at a certain index by one, starting from a specified initial value. In simple terms, it's like adding 1 to the value at that particular position, but for each step, you subtract 1 instead. This can be useful when dealing with large numbers or as part of the design of algorithms in which you want to compute values on the fly without storing
