Write a recursive C$++$ function that will use the prototype void remove$\_$every$\_$ith$($std::string & str$,$ int ith$)$;

This function should take a string, and it must remove every ith character from the string. Your code must not create a new string variable and use no loops.

Example

With the string $"$WE$!$ A$\%$RER H&AVGINQG OSOk MyUC$*$H IFUBN!!" and ith is $3$ the string should be changed to $"$WE ARE HAVING SO MUCH FUN!"
