The Bonus Shift Calculator

A consultant works several shifts in a day. The company pays a 'bonus rate' during specific time windows. Given the consultant's work intervals and the bonus time windows, calculate the total duration the consultant was working while a bonus window was active. All intervals are inclusive. Input Format: - Line 1: N (number of work shifts). - Next N lines: start and end of each shift. - Next line: M (number of bonus windows). - Next M lines: start and end of each bonus window. Output Format: - Total bonus time (integer). Example: Input: 1 9 17 2 0 10 16 24 Output: 2 (Explanation: Intersection of [9,17] with [0,10] is [9,10] length 1. Intersection with [16,24] is [16,17] length 1. Total 2.)
