Given two strings s and t. Check, or a string s is a subsequence of string t.

Input

Two nonempty string s and t, containing only letters and digits (|s| ≤ 100, |t| ≤ 300).

Output

If the string s is a subsequence of the string t, output two lines: "YES" (without the quotes) and the minimum amount of characters in a string of indices t (indexing starts at 0), which is made up of a string s.

If the string s is not a subsequence of the string t, output "NO" (without quotes).
