WebA bit array (also known as bitmask, [1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly. WebWhereas, if the string value does not exist in the array then it will return an iterator pointing to the end of the array arr. Now after the function std::find() returns an iterator, we need check if the iterator is valid or not.
