* When to use lower_bound vs binary_search :cpp:binary-search:algorithm:retrieval::recognition:

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).
