It's easier just to do it yourself rather than wasting time asking in an online forum.

Solution 3

There are many ways, the problem will be for you to work it out for any set of strings.

E.g:

Java

"book".replace("oo","ooxxxok");

or use substring to cut

Java

string bo="book".substring(0,2); string ok="book".substring(2,2)

then add together

Java

string s = bo.concat("xxxx").concat(ok);
