+num stores a random integer between minimum (1) and maximum (100), inclusive.
+
+Breakdown:
+1. Math.random() generates a decimal number between 0 (inclusive) and 1 (exclusive).
+2. Multiplying by (maximum - minimum + 1) scales the range to 0–100.
+3. Math.floor() removes the decimal part, producing integers from 0–99.
+4. Adding minimum shifts the range to 1–100.
