In this task, you are given a date in a particular format and you need to convert to another format. If given format is "dd/mm/yyyy" then convert to "mm/dd/yyyy". If given format is "mm/dd/yyyy" then convert to "dd/mm/yyyy".

09/14/1656, input_format=mm/dd/yyyy
14/09/1656
Since there is no 14th month, the input format is "mm/dd/yyyy". We have to convert it to "dd/mm/yyyy", so the answer is "14/09/1656"..
