Variable Description
Type	Name	Purpose	Scope
BufferedReader	br	To intake number of	Within the function
		boxes	‘takeBoxes()’
int	n	Stores the number	Within the function
		of boxes	‘takeBoxes()’
Int	no	Value of ‘n’ is	Within the function
		assigned on it so	‘takeBoxes()’
		that we can access
		the value afterwards
Int	x	Stores the number	Within the function
		of boxes of the	‘takeBoxes()’
		specified size
Int	cartoons	Holds the number of	Within the function
		cartoons used in	‘takeBoxes()’
		storing the boxes
Int	size	Holds the size of	Within the function
		cartoons	‘takeBoxes()’

Algorithm

Step 1: Create int type variables ‘n’, ‘no’, ‘x’, ‘cartoons’ and ‘size’ with 48 as initial value in size.

Create BufferedReader object ‘br’.

Step 2: Store the number of boxes in variable ‘n’ and assign the value in another variable ‘no’.

Step 3: Check the validity of the value stored in ‘n’. If invalid number of boxes is entered, exit from the program otherwise continue.

Step 4: Repeat the step nos 4 to 10 until value in size becomes 0

Step 5: Divide ‘n’ by ‘size’ and if it is not equal to 0, store the quotient in ‘x’ which represents the number of cartoons of size ‘size’.

Step 6: Display size of the cartoon, number of that sized cartoon and number of boxes in those cartoons.

Step 7: Increase the value of the variable cartoons by the number of that sized cartoons used.

Step 8: Reinitialise ‘n’ with the remaing boxes

Step 9: Reduce the value of size to half of the previous value, which represents the capacity of the next sized cartoons. If the value becomes 0, go out of step 10 other go to step 10

Step 10: if the value of ‘n’ becomes less than 6 but greater that 0 then display ‘n’ as remaining boxes and go to step 11. if the value of ‘n’ becomes 0 then display ‘n’ as remaining boxes and go to step 11. Otherwise go to step 4

Step 11: Display ‘no’ and ‘cartoons’ to show how many boxes and how many cartoons used import java.io.*;
