( 1429 )	C	Oranges and Apples	PROGRAMMING	constructive algorithms sortings		2500

B"In 2N xe2 x80 x89- xe2 x80 x891 boxes there are apples and oranges. Your task is to choose N boxes so, that they will contain not less than half of all the apples and not less than half of all the oranges. The first input line contains one number T -- amount of tests. The description of each test starts with a natural number N -- amount of boxes. Each of the following 2N xe2 x80 x89- xe2 x80 x891 lines contains numbers ai and oi -- amount of apples and oranges in the i-th box (0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89ai, xe2 x80 x89oi xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89109). The sum of N in all the tests in the input doesn't exceed 105. All the input numbers are integer. For each test output two lines. In the first line output YES, if it's possible to choose N boxes, or NO otherwise. If the answer is positive output in the second line N numbers -- indexes of the chosen boxes. Boxes are numbered from 1 in the input order. Otherwise leave the second line empty. Separate the numbers with one space."...
