spoj#BLSUMSEQ. Sum of subsequences
Sum of subsequences
English | Vietnamese |
Given an positive integer n and a sequence a1…an. There are q queries. Each query has one of two formats :
- Format 0 l r k : you need to output the k-th smallest positive integer that can’t be partition into a sum of any subsequence of al...ar
- Format 1 l r x : you need to output the numbers of ways to partition x into a sum of a subseqence of al...ar (or the numbers of subsequence that sum of all its elements equal to x) (modulo 232)
Input :
- Fist line : two positive n and q (1 ≤ n ≤ 100, 1 ≤ q ≤ 10000)
- Second line : n positive a1…an (0 ≤ ai ≤ 100)
- Next q lines : each line denotes a query with one of two format listed above (1 ≤ l ≤ r ≤ n, 1 ≤ k ≤ 109, 0 ≤ x ≤ 109)
Output :
- q lines : the i-th line is the answer of i-th query.
