My list is apparently empty, but I don't understand why...
package com.codegym.task.task07.task0716;
import java.util.ArrayList;
/*
R or L
*/
public class Solution {
public static void main(String[] args) throws Exception {
ArrayList<String> list = new ArrayList<String>();
list.add("rose"); // 0
list.add("love"); // 1
list.add("lyre"); // 2
list = fix(list);
for (String s : list) {
System.out.println(s);
}
}
public static ArrayList<String> fix(ArrayList<String> list) {
for(int i = 0; i < list.size() ;) {
if(list.contains("r") && list.contains("l") || !list.contains("r") && !list.contains("l")){
i++;
}
else if(list.contains("r")){
list.remove(list.indexOf(list.get(i)));
}
else if(list.contains("l")){
list.add(i, list.get(i));
i+=2;
}
}
return null;
}
}
