My idea about the problem is finding each occurrence of the end string and mark these in a array with a 1. Then prefix sum that array for range sum queries. After that on the suffix array of t+'#'+Sbegin iterate over the sorted suffixes which have Sbegin as a prefix to find how ...
1) make suffix array and lcp array 2)count the length of suffix and subtract the lcp from this length of next lexographically sorted suffix 3)summation of all the answers obtained in step 2 More formally ans=0; //pos[i]=rank of a number starting at ith position//sa[i]=i'th rank ...
We will denote the length ofRbynand the total length of strings in the collection by\(N=\sum _{d=1}^m |S_d|\). As before, we assume that the end-of-string character\(\#\)ofRis strictly smaller than those of the strings in the collection\({{\mathcal {C}}}\). We are inter...
We reduced the suffix array construction problem to a number of parallel primitives such as prefix-sum, radix sorting, random gather and scatter from/to the memory. Thus, the performance of the algorithm merely depends on the performance of these primitives on the particular shared memory ...
In practice, this is done by first comparing each triplet against its predecessor, storing a flag of 1 whenever they are unequal, and then doing a prefix-sum of the list of flags. We use the same flagging method as Deo and Keely to tell if S12 are fully sorted (line 6 right and ...
The second algorithm improves the first algorithm to O(n) time and space in the worst case. The improved algorithm requires only 7n bytes of storage, including the n bytes for the original string, and the 4n bytes for the suffix array. We take a general divide and conquer approach: ...
It is guaranteed that the sum of 𝑛n in all test cases does not exceed 2⋅105. Output For each test case, print one integer — the minimum number of operations Gildong has to perform in order to make all elements of the array equal. ...

In 1992, Gusfield et al. [8] presented the first optimal O(N+m2) time algorithm for the APSP using (generalized) suffix trees [21], where N is the sum of string lengths. This solution is optimal because the input size is N and the output size is m2. Almost 20 years later, Ohle...
