Apart from its use in the Lowest Common Ancestor (LCA) problem, sparse tables are primarily employed for the following purposes:
- It can be used as a replacement for a Segment Tree in problems where there are no updates, resulting in improved time complexity.
- It is also utilized for binary lifting operations.
It's worth noting that the time complexity of `log2()` function in C++ is logarithmic, so pre-calculating the logarithm values is a smart move to optimize performance.
