20. An array of size 5X5 is given to us. The elements from 1 to 25 are to be inserted in the array, such that starting from a particular position for an element i, the next element i+1can be inserted only at the mentioned positions (u,v), and if these all positions are occupied then it returns giving a count of how many positions have been occupied in the array:
(u,v) = (x+/-3 , y)
(u,v) = (x , y+/-3)
(u,v) = (x+/-2 , y+/-2).

Programmin section 1.30 hrs 4 question.
1)Seat Planing
Write a function for seat allocate and seat reserved.Seat allocate array and seat reserver array.Seatallocate array is of 10*20 and each row and column represent A1,A2....;B1,B2.....;........J1,J2... andso on i.e row are A to J whereas col starts from 0 to 19.Each cell in the table represent either 0 or1. 0 rep seat available , 1 repr seat reserved. Seat allocation starts from highest to lowest.And row j is highest, i is second highest and so on.Max 20 seats can be booked at a time. if seat is available print the seat no like "B2" i.e (2 row, 3 col)and seat is booked." otherwise Print "Seat is not available."

2) A string of charater is given.Find the highest occurance of a character and display that character.
