Minimal Absolute Difference

There are N pyramids in a line.You are given their heights as a list of integers.Write a program to find the minimum absolute difference between the heights of any two different pyramids.

Input

The input is a single line containing space-separated integers.

Output

The output should be a single line containing the minimum absolute difference of any two different pyramid heights.

Explaanation

Given Pyramid heights are 7 1 5.

The absolute difference between the heights of any two different pyramids are

Matrix Triangle Sum

You are given a square matrix of size NxN, write a program to print the sum of upper and lower triangular elements.

Upper triangle consists of elements on the anti-diagonal and above it. The lower triangle consists of elements on the anti-diagonal and below it.

Explanation:

In the example,if the given matrix is

1 2 3

4 5 6

7 8 9

The upper triangle consists of elements on the anti-diagonal and above on it.

1 2 3

4 5

7

The sum of upper triangle elements is (1+2+3+4+5+7) equal to 22.

The lower triangle consists of elements on the anti-diagonal and below to it.

3

5 6

7 8 9

The sum of lower triangle elements is (3+5+6+7+8+9) equal to 38.

So the output should be

22

38

Sample Input

3 3

1 2 3

4 5 6

7 8 9

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.

you are given an m*n matrix.write a program to compute the perimeter of the matrix and print the result.perimeter of a matrix is defined as the sum of all elements of the four edges of the matrix

m = no of rows

n = no of columns

Ex: [1 2 3 4

5 6 7 8

9 10 11 12]

Perimeter : 1+2+3+4+8+12+11+10+9+5 = 65

Note: take input from the user.

Product of the String

You are given an alphanumeric string S.Write a program to multiply all the charcters(except trailing zeroes) in S and print the output.

Rules for multiplication:

• If the character is digit, multiply its value.
• If the character is an alphabetic character, multiply the product of digits of its ASCII value.

Input

The first line contains a string S.

Output

The output should be a integer denoting the product of characters.

Explanation

For N = 123a4

ASCII value of a is 97.

Product of digits of ASCII value of a is 9 *7 = 63.

Therefore the product of characters is 1*2*3*4*63*4 = 1512.
