Imagine you are writing a version of the computer game Minesweeper. Use arrays to create and store a minefield on a $2020$ grid. Place ten mines randomly on the grid, then display the grid, using asterisks $(*)$ for the mines and periods $(.)$ for the empty squares. $($Hint: To return a random number between $0$ and $19$ inclusive, use rand $(0,19).)$ You have to write the code in php and html$.$
