Python Day 6

The Let's review solution for python keeps breaking at line 3
The code requires more input than provided by stDIN.
The code breaks when you try to initialize "NumberOfStrings" input variable as an integer which gives an error as an alphabet cannot be conerted to an integer

The solution is to take out the "NumberOfStrings" variable.
