Lets suppose correct data formats are 01/01/2020 or 1/1/2020 or 01/1/2020 or 1/01/2020.

So whats happening, i am receiving dates in this format sometimes 01**7**01/2020 so here slash (/) changes into 7, so i want to fix this issue. So that even if slash becomes something else, it can skip 7 and gives me the exact date.

Please assume second slash can also change like first.
