Write the needed code to make the program runs correctly.

The program prompts the user to input a non-zero

positive integer, then prints out the patterns shown

in the sample runs below.

You must use repetition structure such as for-loop or

while-loop.

The sample runs are as follows.

Sample Run 1:

Key in an integer +ve value: 7

7

1

1 2

1 2 3

1 2 3 4

1 2 3 4 5

1 2 3 4 5 6

1 2 3 4 5 6 7

Sample Run 2:

Key in an integer +ve value: 15

15

1

1 2

1 2 3

1 2 3 4

1 2 3 4 5

1 2 3 4 5 6

1 2 3 4 5 6 7

1 2 3 4 5 6 7 8

1 2 3 4 5 6 7 8 9

1 2 3 4 5 6 7 8 9 10

1 2 3 4 5 6 7 8 9 10 11

1 2 3 4 5 6 7 8 9 10 11 12

1 2 3 4 5 6 7 8 9 10 11 12 13

1 2 3 4 5 6 7 8 9 10 11 12 13 14

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
