Minimum Distance Between Words [AMAZON]

     

A string S is passed as the input. Two words W1 and W2 which are present in the string S are also passed as the input.
 The program must find the minimum distance D between W1 and W2 in S (in forward or reverse order) and print D as the output.

Input Format:
The first line will contain S.
The second line will contain W1.
The third line will contain W2.

Output Format:
The first line will contain D - the minimum distance between W1 and W2 in S.

Boundary Conditions:
Length of S is from 5 to 200.

Example Input/Output 1:
Input:
the brown quick frog quick the
the
quick

Output:
1
Explanation:
quick and the are adjacent as the last two words.
 Hence distance between them is 1.

Example Input/Output 2:

Input:
the quick the brown quick brown the frog
quick
frog
Output:
3

        String src=sc.next();
        String dest=sc.next();
