Length of the string str.
Length of the string X.
Stores the dp states.
Fill first row of dp [ ] [ ].
If X [ j ] matches with str [ 0 ].
If s [ i ] is equal to X [ j ].
Update state after removing str [ i [.
Update state after keeping str [ i ].
If str [ i ] is not equal to X [ j ].
Print the minimum number of characters removals.
Driver Code.
Input.
