Problem:
Given a string of even length, return the first half. So the string "WooHoo" yields "Woo".
firstHalf("WooHoo") → "Woo"
firstHalf("HelloThere") → "Hello"
firstHalf("abcdef") → "abc"
Solution:
public String firstHalf(String str) {
int half = str.length() / 2;
return str.substring(0, half);
}
public String firstHalf(String word) {
ReplyDeletereturn word.substring(0, word.length() / 2);
}
public String firstHalf(String str) {
ReplyDeleteint s1 =str.length(), half =s1/2;
return str.substring(0,half);
}
tried all codes and they failed, the correct code is this following:
ReplyDeletepublic String theEnd(String str, boolean front) {
int len = str.length();
String s1 = new String();
if(front){
s1 = str.substring(0,1);}
else{
s1 = str.substring(len-1);
}
return s1;
}
