Python famously has a concept of DRY (Don't Repeat Yourself), which means that when you're starting to see multiple calls to a function, or repeating the same lines, that there is an opportunity for refactoring. You might also get some constant-factor time wins by iterating over the lists with enumerate instead of doing the for index in range() thing, and minimizing the number of extra variables you allocate.

This can be done by: In the code, we choose a random number from all possible cells in the grid. Ow, I wonder how you would reveal those mines. Always use words that explain to readers what the code does through proper variable names. Given an array of strings, return another array containing all of its longest strings. A non-negative integer representing the heaviest weight your friend can lift with his or her left arm. Note: The randint function can only be used after importing the random library. Also, mentioning that you know one or two patterns during your interview (you should know them well enough to write them on a whiteboard) can make you stand out from the crowd.

How many neighbours of this cell are mines? Therefore, there must be provision for clearing it constantly. On the completion of input process, the row and column numbers are to be extracted and stored in 'r' and 'c'.
