Given a sorted array A and a target value B, return the index if the target is found. If not, return the index where it would be if it were inserted in order.
You may assume no duplicates in the array.
1 <= |A| <= 100000
1 <= B <= 109
First argument is array A.
Second argument is integer B.
Return an integer, the answer to the problem.
A = [1, 3, 5, 6] B = 5
A = [1, 3, 5, 6] B = 2
5 is found at index 2.
2 will be inserted ar index 1.
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
