evens

Language/Type: Java recursion recursive programming
Author: Whitaker Brand

Write a method evens that accepts an integer parameter n and that returns the integer formed by removing the odd digits from n. The following table shows several calls and their expected return values:

Call Valued Returned
evens(8342116); 8426
evens(4109); 40
evens(8); 8
evens(-34512); -42
evens(-163505); -60
evens(3052); 2
evens(7010496); 46
evens(35179); 0
evens(5307); 0
evens(7); 0

If a negative number with even digits other than 0 is passed to the method, the result should also be negative, as shown above when -34512 is passed. Leading zeros in the result should be ignored and if there are no even digits other than 0 in the number, the method should return 0, as shown in the last three outputs.
