delDel

Given a string, if the string “del” appears starting at index 1, return a string where that “del” has been deleted. Otherwise, return the string unchanged.

delDel(“adelbc”) ? “abc”
delDel(“adelHello”) ? “aHello”
delDel(“adedbc”) ? “adedbc”

public String delDel(String str) {
if (str.length()>=4 && str.substring(1, 4).equals("del")) {
return str.substring(0, 1) + str.substring(4);
}
return str;
}
