/* Sample Output

Line 1: !found evaluates to false

Line 2: x > 4.0 evaluates to true

Line 3: !found && (x >= 0) evaluates to false

Line 4: !(found && (x >= 0)) evaluates to false

Line 5: x + y <= 20.5 evaluates to true

Line 6: (n >= 0) && (n <= 100) evaluates to true

Line 7: ('A' <= ch && ch <= 'Z') evaluates to true

Line 8: (a + 2 <= b) && !flag evaluates to true
