17.for (int i = 2; i < n; i += 2) { //In this part, condition will be i<=n or else it will also

19. }

System.out.println(Arrays.stream(solve(a, queries, updates))
.mapToObj(String::valueOf)
.collect(Collectors.joining("\n")));

I tried type casting this to char because earlier it was returning ascii values of all the characters appended. Works fine now.
