This article is about queue implementation using array in C++. Queue as an Abstract data Type Queue is an ordered data structure to store datatypes in FIFO (First in First Out) order. That means the element which enters first is first to exit(processed). It’s like the normal queue in ...

当你使用 std::pair<int, int> 作为std::priority_queue 的元素时,你需要指定比较函数,因为默认情况下,std::priority_queue 使用operator< 来比较元素,而对于 std::pair,这意味着它会首先比较第一个元素,如果第一个元素相同,则比较第二个元素。 示例代码 代码语言:txt 复制 #include <iostream> #in...
