Chef has a sequence of integers A1,A2,
Chef has a sequence of integers A1,A2,...,AN
A1,A2,...,AN. He takes a sheet of paper and for each non-empty subsequence B
B of this sequence, he does the following:
- For each integer which appears in B
- B, count its number of occurrences in the sequence B
- B.
- Choose the integer with the largest number of occurrences. If there are several options, choose the smallest one.
- Finally, write down the chosen integer (an element of B
- B) on the sheet of paper.
For each integer between 1
1 and N
N inclusive, find out how many times it appears on Chef's sheet of paper. Since these numbers may be very large, compute them modulo 1,000,000,007
1,000,000,007 (10
9
+7
109+7).
