How to Find Element in Vector in C++? As already discussed, the find() function is used to find the elements in the vector in C++, which finds the very first occurrence of the element in the sequence having a linear time complexity. It takes 3 arguments as input, i.e. first, last, ...

Unlike, std::set, flat_set stores the elements in the sorted vector-like structure, providing efficient memory usage and cache locality. The time complexity of this function is O(log n). Syntax Following is the syntax for std::flat_set::find() function. iterator find( const Key& key )...
