Time Complexity
int lcs_length(char * A, char * B) { if (*A == '\0' || *B == '\0') return 0; else if (*A == *B) return 1 + lcs_length(A+1, B+1); else return max(lcs_length(A+1,B), lcs_length(A,B+1)); } what is worst case time complexity of $\text{lcs_length}$ if size of $A$ is $m$ and size of $B$ is $n$? O($2^{m+n}$) O($2^{n}$) O($2^{mn}$) O($2^{max(m,n)}$) none of these
