(This consisted of Two programs to be solved in 1 hour.)
A sparse matrix is a matrix in which a node with val=0 is not represented. The whole matrix is represented by a Linked list where node typedef struct Node
int row;
int col;
int value;
sparsematrix next;
} Element, *sparsematrix;
The problem is, if there are two matrix given suppose m1 and m2, then add them and return the resultant sparsematrix.
If suppose there are N functions say from 0,1,2,… N-1 and it’s given that A[i][j]=1 if the function i contains a call to
func. j otherwise A[i][j]=0, then write a function that will form groups of related functions and print them line by line and at the end print the number of total groups
