# Python Program to print digit pattern

• Difficulty Level : Basic
• Last Updated : 23 Aug, 2022

The program must accept an integer N as the input. The program must print the desired pattern as shown in the example input/ output. Examples:

Input : 41325 Output : |**** |* |*** |** |***** Explanation: for a given integer print the number of *’s that are equivalent to each digit in the integer. Here the first digit is 4 so print four *sin the first line. The second digit is 1 so print one *. So on and the last i.e., the fifth digit is 5 hence print five *s in the fifth line. Input : 60710 Output : |****** | |******* |* |

Approach Read the input For each digit in the integer print the corresponding number of *s If the digit is 0 then print no *s and skip to the next line

## Python3

 `# function to print the pattern``def` `pattern(n):` `    ``# traverse through the elements``    ``# in n assuming it as a string``    ``for` `i ``in` `n:` `        ``# print | for every line``        ``print``(``"|"``, end ``=` `"")` `        ``# print i number of * s in``        ``# each line``        ``print``(``"*"` `*` `int``(i))` `# get the input as string        ``n ``=` `"41325"``pattern(n)`

Output:

```|****
|*
|***
|**
|*****```

Time complexity: O(n) since one traversal of the array is required to complete all operations hence the overall time required by the algorithm is linear
Auxiliary Space: O(1) since no extra array is used so the space taken by the algorithm is constant

Alternate solution that takes integer as input :

## Python3

 `n ``=` `41325``x ``=` `[]``while` `n>``0``:``    ``x.append(n``%``10``)``    ``n ``/``/``=` `10``for` `i ``in` `range``(``len``(x)``-``1``,``-``1``,``-``1``):``    ``print``(``'|'``+``x[i]``*``'*'``)` `# code contributed by Baivab Dash`

Output:

```|****
|*
|***
|**
|*****```

Time complexity: O(n) since one traversal of the array is required to complete all operations hence the overall time required by the algorithm is linear
Auxiliary Space: O(n) since an extra list is used so in the worst case the space taken by the algorithm will be linear
