Firstly map each value of array B with index, say in "map datastructure"

 After that update the value of array A which are in B as the key value from "map"
A = [1,3,4,2,5,6] after updating we get C as
C = [   1,2,   4,3]
from C find the longest increasing subsequence and subtract the length of it from length of B.

ans =  ( len(B)-len(C))
