Problem Statement
		
		
			We have a circular pizza.
Takahashi will cut this pizza using a sequence 
AA of length 
NN, according to the following procedure.
		
		
			- 
				First, make a cut from the center in the 1212 o'clock direction.
			
- 
				Next, do NN operations. The ii-th operation is as follows.
				
					- 
						Rotate the pizza A_iAi degrees clockwise.
					
- 
						Then, make a cut from the center in the 1212 o'clock direction.
					
 
		
			For example, if 
A=(90,180,45,195)A=(90,180,45,195), the procedure cuts the pizza as follows.
		
		
			
 
		
		
			Find the center angle of the largest pizza after the procedure.
