Sequential Mode: This mode searches for the private key in a sequential manner, from a starting point and incrementing step by step. It is straightforward but can be slow if the target key is far from the starting point.

Backward Mode: In this mode, the search starts from a specified point and moves backward. This can be useful if you have reason to believe the key might be located before a certain point.

Both Mode: This mode combines both forward and backward searching. The algorithm searches in both directions simultaneously, which can increase the chances of finding the key faster compared to only moving in one direction.

Random Mode: Instead of following a linear path, the search jumps to random positions. This mode can help in scenarios where the key is not expected to be near the starting point and can be located anywhere in the search space.

Dance Mode: This is a more advanced and less predictable search pattern, potentially combining aspects of the other modes in a dynamic way. The exact implementation details can vary, but the goal is to maximize the coverage of the search space and increase the likelihood of finding the key efficiently.
