Description
Question 1. Ask the user to enter a random binary array having the first K numbers equal to 0 and the rest equal to 1. Write a function to find the position of K that splits the 0s and 1s. The time complexity of your solution should be O(logn).)
(Example: input: a = [ 0 0 0 1 1] ➔ output: K = 3)
Question 2. Given two sorted arrays each of size n. Find the median of an array resulting from merging the two arrays. (Hint: You could use the same approach of binary search algorithm. The time complexity of your solution should be O(logn).)
Example 1:
a1 = [0, 2, 10, 26, 68], >> median = 10 a2 = [1, 11, 18, 20, 41], >> median = 18 Output: Median = (11+18)/2 = 14.5
Example 2: a1 = [5, 6, 14, 26], >> median = (6+14)/2 = 10 a2 = [3, 41, 88, 100] >> median = (41+88)/2 = 64.5 Output: Median = (14+26)/2 = 20
Example 3:
a1 = [5, 10], a2 = [2, 41]
Output: Median = {max(a1[0], a2[0]) + min(a1[1], a2[1])}/2 = {max(5,2)+min(10,41)}/2 = {5+10}/2 = 7.5
