Day 6: Let’s Review

• Instructions:
  • Given a string s of length N that is indexed from 0 to N - 1, print it’s even-indexed and odd-indexed characters as space-separated strings on a single line
  • Example: s = adbecf prints out: abc def
  • Constraints
    • 1 <= t <= 10 : (t is number of test cases)
    • 2 < length of s <= 10000
