Maximum Unique Segment
All submissions for this problem are available.
Read problems statements in mandarin chinese, russian and vietnamese as well.
You are given 2 arrays W = (W1, W2, .., WN) and C = (C1, C2, .., CN) with N elements each. A range [l, r] is unique if all the elements Cl, Cl+1, .., Cr are unique (ie. no duplicates). The sum of the range is Wl + Wl+1 + ... + Wr.
You want to find an unique range with the maximum sum possible, and output this sum.
- The first line of the input contains an integer T, denoting the number of test cases. The description of each testcase follows.
- The first line of each test case contains a single integer N, denoting the size of the arrays.
- The second line contains N space-separated integers : C1, C2, .., CN.
- The third line contains N space-separated integers : W1, W2, .., WN.
For each testcase, output a single integer in a new line, which should be the maximum possible sum of an unique range.
- 1 ≤ T ≤ 100
- 1 ≤ N ≤ 1000000
- 0 ≤ Ci < N
- 0 ≤ Wi ≤ 1000000000
- 1 ≤ Sum of N over all test cases ≤ 1000000
- Subtask #1 (30 points): Sum of N over all test cases ≤ 10000
- Subtask #2 (70 points): Original constraints
Input: 1 5 0 1 2 0 2 5 6 7 8 2 Output: 21
The range [2, 4] is an unique range because (1, 2, 0) has no duplicates. Its sum is 6 + 7 + 8 = 21. This is the maximum possible, and hence is the answer.
