This passes all cases barr 5. Seems to be an issue with test case 5 as others have pointed out.
public class Solution { public static void main(String[] args) { Scanner s = new Scanner(System.in); int t = s.nextInt(); String [] pair_left = new String[t]; String [] pair_right = new String[t]; for (int i = 0; i < t; i++) { pair_left[i] = s.next(); pair_right[i] = s.next(); } HashSet<String> strings = new HashSet<String>(); // counter int lines = 0; for (int i = 0; i < t; i++){ String concat = pair_left[i] + " " + pair_right[i]; if(!strings.contains(concat)){ strings.add(concat); lines++; } System.out.println(lines); }
