The nucleotide bases from which DNA was built is A (adenine), C (cytosine), G (guanine), and T (thymine). Sometimes if the DNA of the living creatures has the same substring, and the length is beyond a certain percentage of the Whole length, we many consider whether the living creature

One TopCoder article introduces a very interesting alternative solution to longest Common sequences problem.It is based on this statement (http://community.topcoder.com/tc?module=Staticd1=tutorialsd2= stringsearching): The important point and allows us to use BS are the fact that if the given strings has a common substring of length n, th EY also has at least one common substring of any length m So we can start b-search on string length of S1, for S2, since current substr Len are fixed,

Lis subproblem: DP [I] records the length of the longest ascending subsequence ending with a [I] DP [1] = 1; Subproblem of LCS: DP [I] [J] records the length of the longest common subsequence of S1 ending with I and S2 ending with J N1 = strlen (S1 + 1);

algorithm is reduced to O (Nlogn), with a very significant increase. It is important to note that d[] does not record the longest ascending subsequence that conforms to test instructions after the algorithm is finished!HDU 1950 Bridging signals1#include 2#include 3 #defineMAXN 400054 5 intA[maxn],d[maxn],len;6 7 intBinary_search (inti)8 {9 intLeft,right,mid;Tenleft=0, right=Len; One while(leftRight ) A { -Mid = left+ (right-left)/2; - if(D[mid]>=a[i]) right=mid; the
