The complete seating arrangement is divided into 3 sections i.e S1, S2 and S3.
We have to design a seating arrangement for families. Each family comprises of exactly "4" members in it.
- You need to create a function which accepts 2 parameters: 1) No. of rows ("r" -> Integer) 2) Blocked seats (For example = [ a1, a3, b2, c1, c6 ,...])
- While making the arrangement, you have to take this into consideration that all 4 members can seat in multiple rows but adjacent to each other.
- Such cases like ['a1','b1','c1','d1'], ['e1','f1','g1','h1'], ['g1','h1','i1','j1'], etc are not possible.
- Valid cases - ['a1', 'b1', 'c1', 'a2'] (2nd row), ['a1','b1','c1','b2'], ['a1','b1','c1', 'c2'] , ['d1', 'e1','f1','g1']
- You need to find the maximum number of families that can get accommodated in the theater.
- Write down the pseudo code/logic how you would solve this
- Provide a working solution in the language of your choice to achieve this.
