► Problem açıklaması:
Today, we’re getting started with Exceptions by learning how to parse an integer from a string and print a custom error message. Check out the Tutorial tab for learning materials and an instructional video!
Read a string, S, and print its integer value; if S cannot be converted to an integer, print Bad String.
Note: You must use the String-to-Integer and exception handling constructs built into your submission language. If you attempt to use loops/conditional statements, you will get a 0 score.
A single string, S.
Print the parsed integer value of S, or Bad String if S cannot be converted to an integer.
Sample Input 0
Sample Output 0
Sample Input 1
Sample Output 1
Sample Case 0 contains an integer, so it should not raise an exception when we attempt to convert it to an integer. Thus, we print the 3.
Sample Case 1 does not contain any integers, so an attempt to convert it to an integer will raise an exception. Thus, our exception handler prints Bad String.
