pair in stack

The pair in the stack allows us to store pairs of elements in a stack. First, we include the necessary header file for using the stack and pair in C++. Then, we create a stack using the pair with the desired data types. Next, we push pairs into the stack using the make_pair function. To access the elements of the pair in the stack, we use the top function to retrieve the top pair and then access the individual elements using the dot operator. Finally, we can pop pairs from the stack using the pop function.
