IAPCR2E - Ballons Revisited

no tags 

You have w white, r red, g green and b blue balloons. To make a single student happy you need exactly four balloons. All four balloons given to a student shouldn't have the same color. What is the maximum number S of happy students if we know number of balloons of each color?

Your task is to write a program that for given values w,r, g and b will find the S.


Input starts with an integer T (≤ 20000), denoting the number of test cases.

Each test case contains four integers w,r, g and b (0 ≤ w,r, g, b ≤ 10^9) — the number of white,red, green and blue balloons respectively. The numbers are separated by exactly one space.


For each test case print a single integer S — maximum number of happy students.


2 2 1 3
1 1 4 1

Case 1: 2
Case 2: 1

@ test500_spoj
(w=1,r,1,g=0,b=2)=1 [ You can give four balloons to second child as all of them are not of same colour]
Answer is : 2

It is misleading. You need to write labels "Case xxx: " otherwise, you will get a wrong answer :(

Why does it say "Case 1: " in the example output? Are we supposed to output _only_ the integer answer or not? Very misleading.

first case: 2w, 2r g, 3b. you can make 2 sets so that each set will contain at least two colors, {w, r, g, b}, and {w, r, b, b}
