Week 4 Unit 3: Exercise

The file numbers.txt contains random integer numbers. There is exactly one number per line. Read the file and output the three biggest numbers in the following form:

2345
223
89

Hint

Read the file line by line, delete the line break. As files can only contain strings, the number must now be converted into an integer. Add the number into a list. When all numbers are in the list, sort the list. Then print out the biggest numbers.
