Throw an element x into the bag.2Takeoutan elementfromthe bag. Given a sequence of operations withreturnvalues, you're going to guess the data structure. It is a stack (Last-In, First-Out), a queue (First-In, First-Out), a priority-queue (Always take out larger elements first) or...
The data structure should have the operation where the data item with the minimum/maximum value is the next item to be deleted. The data structure should also support the function of a calendar queue where elements with the same or similar priority have the same key. For example, all of ...
