为什么我的程序对此程序给出“错误答案”？

Question

I was solving this question in Hackerrank and matched the result in my IDE. But then the answer is not being accepted by Hackerrank.

My code is:

for i in range(1,int(raw_input())):
    print (str(i)*i)  

Please help...

Answer 1

The task says:

Can you do it using only arithmetic operations, a single for loop and print statement?

Use no more than two lines. The first line (the for statement) is already written for you. You have to complete the print statement.

Note: Using anything related to strings will give a score of 0.

This is clear, you cannot use str(i) .
