Omega notation

Omega (Ω) notation describes the lower bound of an algorithm's performance or running time, indicating the best-case or minimum amount of work an algorithm will need, regardless of input size. It tells us that, for sufficiently large inputs, the algorithm will take at least a certain amount of time or resources. Think of it as a guarantee that the process cannot be faster than this bound. Omega helps us understand the minimum resources required, providing insight into the best possible performance while still allowing for potential slower behavior in other cases.
