HackerRank Python Solution - Math Topic - Triangle Quest

• You are given a positive integer N. Print a numerical triangle of height N-1 like the one below:

1
22
333
4444
55555
......

• 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.

Input Format:

• A single line containing an integer, N.

Constraints:

• 1 <= N <= 9

Output Format:

• Print N-1 lines as explained above.

Sample Input:

5

Sample output:

1
22
333
4444

Solution:

for i in range(1,int(input())): #More than 2 lines will result in 0 score. Do not leave a blank line also

    print((10**i)//9 * i)
