Chef has 33 boxes of sizes AA, BB, and CC respectively. He puts the boxes in bags of size DD (A≤B≤C≤DA≤B≤C≤D). Find the minimum number of bags Chef needs so that he can put each box in a bag. A bag can contain more than one box if the sum of sizes of boxes in the bag does not exceed the size of the bag.

Three Boxes solution codechef

• The first line contains TT denoting the number of test cases. Then the test cases follow.
• Each test case contains four integers AA, BB, CC, and DD on a single line denoting the sizes of the boxes and bags.

Test case 11: The sum of sizes of boxes is 2+3+5=102+3+5=10 which is equal to the size of a bag. Hence Chef can put all three boxes in a single bag.

Test case 22: Chef can put boxes of size 11 and 33 in one bag and box of size 22 in another bag.

Test case 33: Chef puts all the boxes in separate bags as there is no way to put more than one box in a single bag.
