Hi, I spent some time learning about how to implement a segment tree, memory efficiently (see [1](https://www.lrvideckis.com/blog/2023/09/01/segtree_memory.html) [2](https://codeforces.com/blog/entry/112755) [3](https://codeforces.com/blog/entry/131551?#comment-1170732)) and want to add more info to [this section](https://cp-algorithms.com/data_structures/segment_tree.html#memory-efficient-implementation) Do you think it's a good idea? I can make a PR
