Java > Warmup-1 > delDel (CodingBat Solution)

Problem:

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"


Solution:

public String delDel(String str) {
  if (str.startsWith("del", 1))
    return str.charAt(0) + str.substring(4, str.length());
  else
    return str;
}

    function delDel(str){
    let a = str.substr(1,3);
    if (a == 'del'){
    return str.replace('del', '');
    } else return str;


    }

    public String delDel(String str) {
    return (str.startsWith("del",1))?str.replace("del", ""):str;
    }
