Submarine Hunt
Using your destroyer, try to locate the position of the enemy
submarine in a 10 X 10 grid, then destroy it with a depth charge.

Saction 10: Applications Programs 185
Make guesses as to where you think the submarine is hiding by
taking sonar readings. Input the location of your destroyer (R,C)
and press [B). If the submarine is in one of the 8 adjacent squares
(or directly under your destroyer), the calculator will display "1."
Otherwise, a "0" will be shown,
When you think you've located the submarine, move your destroyer
directly over it (move to the same square) and drop a depth charge.
Blinking "1's" indicate a hit, while a "0" shows a miss. If you miss,
the submarine will move randomly to one of the 4 adjacent squares
in the same row or column.
To make a more challenging game, press (C] immediately after
inputting the seed. This allows the submarine to move after each
sonar echo as well as after each depth charge miss. The submarine
always moves randomly to an adjacent square in the same row or
column.
A depth charge has a range of 0.9 squares. When you position your
destroyer for a depth charge drop, you may move anywhere on the
board, not just to the center of a square. For instance, a depth
charge dropped from a (2.5, 6.5) location would destroy any
submarine in the center of squares (2, 6) (2, 7) (3, 6) and (3, 7).
Try to destroy the submarine using no more than 10 sonar readings
and 1 depth charge. You can check your status any time the display
is steady by pressing (D).
Status format is XX.YY
XX = Number of depth charges fired.
YY = Number of sonar readings.
