The resulting arraylist representation of the heap after deleting (popping) an element would be: [4, 3, 2, 1]. After popping an element from the heap, the heap must be reorganized to maintain the heap property.
An array is a data structure that is used to store a collection of items that all have the same data type. It is an ordered list of elements that can be accessed by their index position in the list. An array is used to store large amounts of data efficiently, as it allows for quick access to each element. It is also used to perform mathematical operations on the data, such as sorting, searching, and filtering. Arrays can be one-dimensional or multi-dimensional, and their size is fixed when they are declared. They can be used to store objects, such as strings and numbers, as well as other data structures, like linked lists and binary trees.
This is done by comparing the values of the parent and the child nodes and swapping their positions to ensure that the parent node has the greater value. In this case, the element 5 was popped, so the heap was reorganized as follows: 4 was swapped with 3, then 3 was swapped with 2, and 2 was swapped with 1, leaving the resulting arraylist representation of the heap as [4, 3, 2, 1].
