Write a program to print a parallelogram pattern with * characters. The size N represents the length (the number of * characters in each line)& breadth ( the number of lines) of the parallelogram.

The slope of the parallelogram T represents the number of extra spaces a line should have in the beginning compared to its next line. The last line of the pattern does not have any spaces in the beginning.

Explanation:

Given N=3 and T=2, each line should have 3 star(*) characters.

The last line should have 0 spaces at the beginning.

Each line has 2 extra spaces characters when compared to its next line.

Input

The input is a single line containing space seperated integers.

Output

The output should be a single line integer.

Explanation

In the example the given prices are 7 1 5 3 6 4.

buying stocks on day two having price 1 and selling them on the fifth day having price 6 would give the maximum profit which is 6 - 1

so the output should be 5.

How to use a loop(for loop or while loop) in a pseudocode algorithm?

Can I have an example?

[int(input()) for _ in range(n)]

in this line how we are using for loop aside of input() function can you explain

in this answer why we are using "_" operator and what is the use with it
