Problem Statement

Ninja luckily found a treasure hidden in his backyard. He found some stones in the treasure box and Ninja thought that these stones could be valuable. He went to a stone expert, and the expert gave him a list ‘JEWELS’ consisting of the names of all valuable jewels. Ninja made the list ‘STONES’ of all stones he found in the treasure. All stones and Jewels are represented by English characters. Now, Ninja wants to know the number of jewels he found in the treasure box. Can you help the Ninja?

Note: ‘JEWELS’ consist of distinct characters and ‘A’ and ‘a’ are treated as two different stone types.

For Example
If ‘STONES’ is “abAAc” and JEWELS is “Acd”.The number of jewels Ninja have is 3.
