(a) Write a linear time ( 6(n) ) divide and conquer algorithm to calculate x", that is x is raised to the power n. Assume x and n are both >=0. (b) Analyze the time complexity of your algorithm in the worst-case by first writing its recurrence relation. (c) Can you improve your algorithm in Part a to accomplish the result in O(log n) time complexity (we still look for a divide and conquer algorithm). If yes, write the corresponding algorithm, write the recurrence relation for its time complexity and analyze it. If no, justify your answer.

(a) Write a linear time ( 0(n) ) divide and conquer algorithm to calculate x", that is x is
raised to the power n. Assume x and n are both >=0.
(b) Analyze the time complexity of your algorithm in the worst-case by first writing its
recurrence relation.
(c) Can you improve your algorithm in Part a to accomplish the result in O(log n) time
complexity (we still look for a divide and conquer algorithm). If yes, write the corresponding
algorithm, write the recurrence relation for its time complexity and analyze it. If no, justify
your answer.
