Given two sequences X and Y:

X=$\langle$ a, b, c, b, d, a, b $\rangle$

Y=$\langle$ b, d, c, a, b, a $\rangle$

The longest common subsequence of X and Y is:

  1. $\langle$ b, c, a $\rangle$
  2. $\langle$ c, a, b $\rangle$
  3. $\langle$ b, c, a, a $\rangle$
  4. $\langle$ b, c, b, a $\rangle$

ans is D simply observe the longest sequence in order (not essentially continuous)common in both 

X=⟨ a, b, c, b, d, a, b ⟩

Y=⟨ b, d, c, a, b, a ⟩
