# String from prefix and suffix of given two strings

Given two strings a and b, form a new string of length l, from these strings by combining the prefix of string a and suffix of string b.

Examples :

```Input : string a = remuneration
string b = acquiesce
length of pre/suffix(l) = 5
Output :remuniesce

obstreperous
6
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach :
1. Get first l letters from string a, and last l letters from string b.
2. Combine both results, and this will be resultant string.

## C++
