Compatible Arrays

2 arrays are said to be compatible if they are of the same size and if the ith element in the first array is greater than or equal to the ith element in the second array for all i.Write a program to find whether 2 arrays are compatible or not.

Input Format:

Input consists of 2n+1 integers. The first integer corresponds to ‘n’ , the size of the array. The next ‘n’ integers correspond to the elements in the first array. The last 'n' integers correspond to the elements in the second array. Assume that the maximum value of n is 15.

Output Format:

Refer sample output for details.

SOLUTION:-

Functions – Matrix Maximum

Write a program to find the maximum element in a matrix using functions.

Function specification:

int findMax(int **a, int m, int n)

The first argument corresponds to the pointer to the matrix.

The second argument corresponds to the number of rows in the matrix.

The third argument corresponds to the number of columns in the matrix.

Input and Output Format:

Assume that the maximum number of rows and columns in the matrix is 10.

Refer sample input and output for formatting specifications.

All text in bold corresponds to input and the rest corresponds to output.

Sample Input and Output :

Enter the number of rows in the matrix

Enter the number of columns in the matrix

Enter the elements of the matrix

The matrix is

2 4

1 3

5 9

The maximum element in the matrix is 9

Function Definitions:

int findMax (int **a, int m, int n)

SOLUTION:-

Functions – Null Matrix

Write a program to find whether the given matrix is null or not using functions.

A null matrix is a matrix in which all its elements are zero.

Function specification:

int checkNull(int **a, int m, int n)
The first argument corresponds to the pointer to an array.

The second argument corresponds to the number of rows.

The third argument corresponds to the number of columns.

The function returns a value of 1 if it is a null matrix and 0 otherwise.

Input and Output Format:

Assume that the maximum number of rows and columns in the matrix is 10.

Refer sample input and output for formatting specifications.

All text in bold corresponds to input and the rest corresponds to output.

Sample Input and Output 1:

Enter the number of rows in the matrix

Enter the number of columns in the matrix

Enter the elements of the matrix

The matrix is

2 4

1 3

0 9

The matrix is not null

Sample Input and Output 2:

Enter the number of rows in the matrix

Enter the number of columns in the matrix

Enter the elements of the matrix

The matrix is

0 0

The matrix is null

Function Definitions:

int checkNull (int **a, int m, int n)

SOLUTION:-

CHECK MY FIRST AND LAST

You have to get input from user multiple strings and then check whether the last character of the first string is equal to the first character of the second string, last character of the second string is equal to the first character of the third string and so on... If the condition satisfies than print "YES" else 'NO'.

Sample input :-

statue

elephant

truck

Output:-

YES

SOLUTION:-
