Recursion, Exception Handling, Searching and Sorting Assignments

1. Make a Sequential search program that takes an array of 5 numbers from the console and a search item, your program should return index of search item or -1 if item is not found. Your program should implement a custom Exception Handler class to detect any exceptions.
2. Make a recursive program that computes the Sum of the First n Natural Numbers: simply adding 1 to n natural numbers. Like 1+2+3 = 6 or 1+2+3+4+5+ .... + n = ?. Your input is n.Your program should implement a custom Exception Handler class to detect any exceptions.
3. Perform a Binary search on the given list. 23, 4, 12, 9, 34, 5, 17, 61, 7 15, 30, 25.

Search for the number 34. Your output should include the comparisons table as shown in the sample screenshot below.
