Implement a function inRange(number, start, end) that checks if a number falls between two numbers.

The function should:

• Return true if number is greater than or equal to start and less than end.
• If end is not provided, use 0 as the start and the provided value as end.
• Swap start and end if start > end.

Examples

inRange(3, 2, 4);     // true
inRange(4, 8);        // true, between 0 and 8
inRange(4, 2);        // false, between 0 and 2
inRange(2, 2, 4);     // true
inRange(5, 2, 4);     // false
