ternary string
You are given a string ss consisting of exactly nn characters, and each character is either '0', '1' or '2'. Such strings are called ternary strings.,For the balanced strings, it may be worthwhile to experiment, and find how many balanced strings have length 1, length 2, and length 3. You should get 2, 5, 14.
