Unique Matrix

You are given a N*N matrix. write a program to check if the matrix is unique or not. A unique Matrix is a matrix if every row and column of the matrix contains all the integers from 1 to N

Input:

The first line contains an integer N.

The next N lines contains N space separated values of the matrix.

Output:

The output contains a single line and should be True if the matrix is unique matrix and False otherwise.

5. Survival of the Biggest (while loop)

by CodeChum Admin

Looping a number and taking away each digit of it is so much fun, but I wanted to try out a much more complex task: getting the largest digit among them all.

Think you can handle the job?

Instructions:

1. Input a non-zero positive integer.
2. Using the same concept as the previous problem, figure out how to separate the digits of a number and determine which of the digits is the largest one, using a while. Afterwards, print the largest digit.
3. Tip #1: Create another variable that will hold the largest digit. Initial its value to a negative integer, like -1, outside the loop.
4. Tip #2: Everytime you get the rightmost digit, check if it is greater than the current largest digit. If it is, set it as the new largest digit.
