Since, elements appeared multiple times, we need to avoid counting the frequency of same element again. For this, we have assigned a -1 value to the already counted elements usingcountedvariable. In the end, elements and their frequency in the array is displayed, here also we are using the...
set::count()是C++ STL中的内置函数,它返回元素在集合中出现的次数。由于set容器仅包含唯一元素,因此只能返回1或0。 用法: set_name.count(element) 参数:该函数接受一个强制性参数element ,该元素指定要返回其计数的元素。 返回值:该函数返回1或0,因为该集合仅包含唯一元素。如果设置的容器中存在该值,则返回1...
