如C++的名著《The C++ Standard Library》中所述: “A map is a sorted associative container that contains key-value pairs with unique keys. Keys are sorted by using the comparison function Compare…The complexity for searching operations is logarithmic in the size of the containers.”(map是一个排...

The unordered_map::find() function in C++ provides a powerful mechanism to efficiently locate the elements within “unordered_map” containers. Its constant average time complexity makes it a preferred choice for search operations in scenarios where the key-value pairs must be accessed swiftly. The...
