C ++ STL's non-mutating algorithms is a set of template functions that do not destroy operation data, it is used for processing sequence data one by one, element search, subsequence search, statistics, and matching. The Count algorithm is used to calculate the number of occurrences of a given value in the container. Two prototypes are used to calculate the number of elements equal to the value on the [first, last) range of the iterator n. The difference is whether the Count N is returned directl
