String de prefijo y sufijo de dos strings dadas

Dadas dos strings a y b , forme una nueva string de longitud l, a partir de estas strings combinando el prefijo de la string a y el sufijo de la string b .
Ejemplos: 
 

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

Input : adulation
        obstreperous
        6
Output :adulatperous
