Given a string S and a list of characters C, print string S after removing all of the characters given in list C. The first line is the string S to be modified. The second line contains integer N, which is the number of different characters to be deleted. The following N lines contain the characters to be deleted. A single string S after deleting all of the characters that are given to be deleted. ## Input The first line is the string S to be modified. The second line contains integer N, which is the number of different characters to be deleted. The following N lines contain the characters to be deleted. ## Output A single string S after deleting all of the characters that are given to be deleted. [samples]

**Definitions** Let $ S \in \Sigma^* $ be the input string over alphabet $ \Sigma $. Let $ N \in \mathbb{Z}^+ $ be the number of characters to remove. Let $ C = \{c_1, c_2, \dots, c_N\} \subseteq \Sigma $ be the set of characters to be deleted. **Constraints** 1. $ N \geq 1 $ 2. Each $ c_i \in \Sigma $ **Objective** Compute the string $ S' $ formed by removing all occurrences of characters in $ C $ from $ S $: $$ S' = \text{filter}_{x \notin C}(S) $$
