Given two sequences of characters, print the length of the longest common subsequence of both se- quences. Sequence 1: Sequence 2: For example, the longest common subsequence of the following two sequences ‘abcdgh’ ans ‘aedfhr’ is ‘adh’ of length 3. Input Input consists of pairs of lines. The first line of a pair contains the first string and the second line contains the second string. Each string is on a separate line and consists of at most 1,000 characters Output For each subsequent pair of input lines, output a line containing one integer number which satisfies the criteria stated above.
