Write a method that returns a string made up of the first character from the first string in array 'strs', then the second character from the second string, the third character from the third string, etc. Except don't use the character 'avoid'. Also, the nth string might not have n or more characters, so you will need to make sure the nth character exists before you try to add it. Look at the test data for examples. You MAY use recursion to solve this, but recursion is NOT required.
