Q2. There were two quizzes and n students. All students attended the first quiz, and all but one attended the second. The teacher kept a single list containing, not in any particular order, the ID's of the students attending the quizzes (where the ID of a student appears twice if (s)he attends both quizzes). The teacher would like to find the ID of the student who was absent from the second quiz. Design three algorithms to solve this problem, with the following complexi- ties, and explain why they have these complexities: 1. (1 point) Algorithm 1: runs in O(n log n) time and uses O(1) additional space; 2. (2 points) Algorithm 2: runs in O(n) time and uses O(n) additional space; 3. (2 points) Algorithm 3: runs in O(n) time uses O(1) additional space
