"Make function called somthing(x) that loops through the vector x and for each number ..." Your code does not currently have a loop within it, which is why it only works for single values. Because the prompt says, "for each number" a for loop is probably a good place to start.
Because you know that the code works for single values, then it means your conditional checks are most likely correct, which is the complex part of the problem. input() is able to receive any size matrix, whether 1x1 for single values, or MxN for more complex inputs. This means the input line most likely doesn't need to be changed.
The only thing left to do then is to create a loop so that the conditions are checked for each number.
