Ex 2 Exercise Objectives • Working with nested lists Problem Description An n x n matrix that is filled with the numbers 1, 2, 3,. .., n° is a magic square if the sum of the elements in each row, in each column, and in the two diagonals is the same value. Write a program that reads in 16 values from the keyboard and tests whether they form a magic square when put into a 4 x 4 table. (print magic square it it is a magic square or NOT magic square ) You need fo test two features: 1. Does each of the numbers 1, 2, .., 16 occur in the user input? 2. When the numbers are put into a square, are the sums of the rows, columns, and diagonals equal to each other?
Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
