  2.  * Task 10*
  3.  * We are given numbers N and M and the following operations:
  4.  * N = N+1
  5.  * N = N+2
  6.  * N = N*2
  7.  * Write a program that finds the shortest sequence of operations
  8.  * from the list above that starts from N and finishes in M.
  9.  * Hint: use a queue.
  10.  * Example: N = 5, M = 16
  11.  * Sequence: 5 ---> 6 ---> 8 ---> 16
