My issue

My code

# cook your dish here
for i in range(int(input())):
    no_digits=int(input())
    if no_digits==1:
        print("3")
    else:
        st="3"*(no_digits-1)
        i=int(st)
        print(3*i+6)

@mjarunshowry
the correct logic would be print n-1 times 9 and one time 3

What’s wrong with my code
Can u help me with a test case?

Your code is theoretically ok, but there’s a reason behind why this apparently easy problem is a "Jump from 2* to 3* "

I’ll give you a hint:
For many languages (0.1 + 0.2) doesn’t equal to 0.3
The reason behind also applies to large numbers in Python.

This approach wouldn’t even work in C or C++

@mjarunshowry
for n=10^4 it won’t work.
