for i in range(1,int(input())+1):
    print(*range(1, i), *range(i, 0, -1), sep="")

Asked for one print statment Asked for on for loop

I'm this close to loosing it with hackerank

Asked for one print statment Asked for on for loop

this is my solution:

for i in range(1,int(input())+1): print((111111111//10**(9-i))**2)

for i in range(1, int(input())+1): print((10**i // 9)**2)

It's a simple math problem:

First, recognize the palindrome has this format: 1 * 1 = 1 11*11 = 121 111*111 = 12321

Second, create a formula with a given value of N ((10**N) - 1) // 9

Now you can square the formula by 2
