Need help with these questions. Functions defined outside such as BigIntegerclass,StringBuilderclass, methods fromMathclass (used as Math.(),such asMath.max(), Math.min(), Math.abs() ...) orIntegerclass (used as Integer.(), such asInteger.parseInt()) or Character class (used asCharacter.(), such as Character.isDigit() can't be used. Cheers
