# Hackerearth What is the string made of? solution

## PROBLEM STATEMENT:

You are given a string, which contains entirely of decimal digits (0-9). Each digit is made of a certain number of dashes, as shown in the image below. For instance 1 is made of 2 dashes, 8 is made of 7 dashes and so on.
You have to write a function that takes this string message as an input and returns a corresponding value in terms of a number. This number is the count of dashes in the string message.
Note:
0 consists of 6 dashes, 1 consists of 2 dashes, 2 consists of 5 dashes, 3 consists of 5 dashes, 4 consists of 4 dashes, 5 consists of 5 dashes, 6 consists of 6 dashes, 7 consists of 3 dashes [though the figure shows that 7 consists of 4 dashes but due to minor mistake in the problem please write your solution assuming 7 consists of 3 dashes], 8 consists of 7 dashes, 9 consists of 6 dashes.
Constraints
• String message will contain at least one digit, but not more than 100
• Each character in code will be a digit ('0'-'9').

## SOURCE CODE:

``#include <iostream>``
``#include <string.h>``
``````using namespace std;
int main() {
int arr[100]={6,2,5,5,4,5,6,3,7,6},ans = 0;
char str[10000] ;
cin>>str;
for(int i=0;str[i]!='\0';i++)
{
int temp = str[i] -48 ;
ans += arr[temp];
}
cout<<ans<<endl;
return 0;
}  ``````

1. The ingredients of string are mentioned in this blog. We will easily find the things that what is string made of. This is a different blog from dissertationteam testimonials developmental work. I am really very sure about the creativity of blogging and some other activities.
