Complexity T(n)
What is the time complexity T(n) of the following portions
of code? For simplicity, you may assume that n is a power of
2. That is, n = 2k for some positive integer k.
a) ?
for (i = 1; i <= n; i++)
{
j = n; cout << i << ? ? j << ? ? << endl;
}
b) ?
for (i = 0; i <= n; i += 2)
{
j = n; cout << i << ? ? j << ? ? << endl;
}
c) ?
for (i = n; i >= 1; i = i/2)
{
j = n; cout << i << ? ? j << ? ? << endl;
}
d)
for (i = 1; i <= n; i++)
{ j = n;
while (j >= 0)
{ cout << i << ? ? j << ? ? << endl;
j = j - 2;
}
}

Seat Reservation prog for the theatre. Write a function for seat allocation for the movie tickets. Total no of seats available are 200. 20 in each row. Each row is referred by the Character, "A" for the first row and 'J' for the last. And each seat in a row is represented by the no. 1-20. So seat in diffrent rows would be represented as A1,A2....;B1,B2.....;........J1,J2... Each cell in the table represent either 0 or 1. 0 rep would seat is available , 1 would represent seat is reserved. Booking should start from the last row (J) to the first row(A). At the max 20 seats can be booked at a time. if seats are available, then print all the seat nos like "B2" i.e (2 row, 3 col) otherwise Print "Seats are not available." and we must book consecutive seats only.
