1) we will be create new array, lenght = max floor
2) we will add to index (if exist by number of floow) value of person time
3) read array from right to left 
4) in cicle (current index of cicle as "floow")
  4.1) if current vlue == 0, then incriminate result and continue
  4.2) if it is firs floow, maybe we need to wite, add current value and continue
  4.3) if curent value GREAT that result, then add value by formula (result = curent value - result)
  4.4) otherwise/else, just incriminate result

that it)
