  Activity
  Eldar uses a controller with a circuit to light 16 LED lamps which are labeled from 1 to 16. When the controller a gives signal to a LED lamp, it changes its state (ON or OFF). In the beginning, all the LEDs are switched OFF. Eldar has found a sequence of lightning: On the 1st second controller lights ON all LED lamps. (1….2….3….) On the 2nd it lights ON the LEDs that are even in the circuit. (2...4...6….) On 3rd second it lights every third LED in the circuit. (3...6...9…) And so it continues in similar way... Which LEDs must be switched ON after the 16th second?
  100 tenge There are (N) number of coins on table. Some of them are tails, and some are heads. How many coins do we need to turn around so that all coins be of the same side? We have total number of coins (N). Next N rows contain the numbers 1 (if a coin is up tail) or 0 (if a coin is up head). Find the minimum number of coins that you must turn. Input: The first line is a total number of coins, next lines are values of tails or head. tails = 1, head = 0 Output: Minimum number of coins that we must turn.
