This can be done using recursion. Let countSubsequenceHelper (A, P, PR ,IDX) be our recursive function. 'IDX' store the index of array element. 'PR' store the product of subsequence and take a variable 'CNT' (initialized to 0) to count the number of subsequences. We start from 'IDX' = 0 and 'P' = -1.

For each test case, print the answer: in the first line print one integer k (1≤k≤n) — the minimum number of subsequences you can divide the string s to. In the second line print n integers a1,a2,,an (1≤ai≤k), where ai is the number of subsequence the i-th character of s belongs to. If there are several answers, you can print any. 730. Count Different Palindromic Subsequences. Given a string s, return the number of different non-empty palindromic subsequences in s. Since the answer may be very large, return it modulo 10 9 + 7. A subsequence of a string is obtained by deleting zero or more characters from the string. A sequence is palindromic if it is equal to the.

Every element of the sequence must appear in exactly one subsequence. Input The first line of input data contains integer n ( 1 ≤ n ≤ 105 ) — the length of the sequence. The second line of input data contains n different integers a1, a2, ..., an ( - 109 ≤ ai ≤ 109 ) — the elements of the sequence.
Step 1: Iterate over the entire String Step 2: Iterate from the end of string in order to generate different substring add the substring to the list Step 3: Drop kth character from the substring obtained from above to generate different subsequence. Step 4: if the subsequence is not in the list then recur.
