Develop a program for sorting an array of numbers, along with finding the index positions of the top 3 maximum values and the sum of those top 3 values. The program should also perform the sorting without using any built-in sorting functions.
Input:
arr = [40, 10, 5, 50, 30]
Output:
sorted_arr: [5, 10, 30, 40, 50]

Implement a binary search algorithm with a given input array. The array will always be sorted in ascending order. The array may contain duplicate elements.
arr = [2, 3, 4, 8, 10, 10, 42, 56, 78, 89]
Note: The binary search algorithm should return the index of the first occurrence of the target element if it is present... | codefeedback | [

Write a python code to find the k-th smallest element in two sorted arrays, where the elements in the arrays are positive integers and are not allowed to be repeated. The time complexity of the code should be O(log(min(m, n))), where m and n are the lengths of the input arrays A and B respectively.
