#2249. Pku3896 Multiprocessor Scheduling

The first line of the input file contains the number T of test cases which are described next. The first line of a test case contains the number N (1≤N≤300) of procedures composing each of the two applications. Then, N lines follow, describing the first application. The j^th of these N lines contains two integers, separated by a blank: P(1,j) and D(1,j). After this, other N lines follow, describing the second application. The j^th of these N lines contains two integers, separated by a blank: P(2,j) and D(2,j). We have 1≤P(i,j)≤10 and 1≤D(i,j)≤15000 (i=1,2; 1≤j≤N). Notice that we may have P(i,j)=P(k,l) – this implies that the procedures (i,j) and (k,l) cannot be executed during overlapping time intervals (notice also that if i=k this would not matter, as the procedures of the same application must be executed sequentially).

The output file must contain exactly T lines with a single number each – the minimum makespan for the corresponding test from the input file. These answers must be printed in the order in which the test cases are given in the input file (i.e. the i^th line of the output file contains the answer to the i^th test case from the input file).
