IAPCR2E - Ballons Revisited |
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
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.
Output
For each test case print a single integer S — maximum number of happy students.
Example
Input: 2 2 2 1 3 1 1 4 1 Output: Case 1: 2 Case 2: 1

@ test500_spoj (w=2,r=2,g=1,b=3)=1 then (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 Last edit: 2016-06-21 08:41:30 |

in frist test case answer should be 1... am i right because... (w=2,r=2,g=1,b=3)=1 then (w=1,r,1,g=0,b=2)=0 answer should be 1; |

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} |
