When to use lower_bound vs binary_search :cpp:binary-search:algorithm:retrieval::recognition:
Front
When should you use std::lower_bound instead of std::binary_search?
Back
Use lower_bound when you need the position/index of the element.
Use binary_search when you only need to know if it exists (bool).
