Given string workString on one line, integer idxBegin on a second line, and integer selectionLen on a third line, replace selectionLen characters with "abcd", starting at index idxBegin.

Ex: If the input is: #include

#include

using namespace std;

int main$()\{$

string workString;

int idxBegin;

int selectionLen;

getline$($cin$,$ workString$)$;

cin $>>$ idxBegin;

cin $>>$ selectionLen;

$/*$ Your code goes here $*/$

cout $<<$ workString $<<$ endl;

return $0$;

$\}$

Fuzzy bear

$4$

then the output is:

Fuzabcdear

Note: Using a pre$-$defined string function, the solution can be just one line of code.
