Array:

An array is defined as a group that consists of similar data types.

The array size must be specified by an “int” value and not long or short.

In Java, all arrays are allocated dynamically.

An array is always indexed, starting from 0.

Example:

//Create an array variable with size 3

int i[] = new int[3];

In the above statement,

The “int” refers the data type of the array.

The “i” refers the name of the array.

The keyword “new” refers the new memory allocation.

The “int[3]” refers the size of the array.

Difference between array size declarator and subscript:

In the above example, “3” is the array size declarator and the index specified for each element in the array is called as subscript...

(Dynamic Programming.) Recall the problem presented in Assign- ment 3 where given a list L of n ordered integers you're tasked with removing m of them such that the distance between the closest two remaining integers is maxi- mized. See Assignment 1 for further clarification and examples. As it turns out there is no (known) greedy algorithm to solve this problem. However, there is a dynamic programming solution. Devise a dynamic programming solution which determines the maximum distance between the closest two points after removing m numbers. Note, it doesn't need to return the resulting list itself. Hint 1: Your sub-problems should be of the form S(i, j), where S(i, j) returns the maximum distance of the closest two numbers when only considering removing j of the first i numbers in L. As an example if L [3, 4, 6, 8, 9, 12, 13, 15], then S(4, 1) = 2, since the closest two values of L' = [3,4,6,8] are 6 and 8 after removing 4 (note, 8-6 = = 2). = Hint 2: For the sub-problem S(i, j),…
