Given an integer, re-arrange the integer such that first and last digit will be at first and second, second and second last digit will be at third and fourth position from left of the re-arranges integer and so on. Example: Input -> 12345678, Output -> 18273645 Input -> 1234567, Output -> 1726354
How to convert an Optional string to integer without throwing exception

You have a function f(p) that returns an array of linked pages e.g f(homepage) = {page1, page2, page3}. Or f(page1) = {page4, page5}. If there is no linked pages function will return null. And we say one site is a good site if we can get to any page of that site in a less than 6 clicks. The task was to write a function that will check is it a good site or not using f(p).
if i type character 'A' in text file and save it, what will be size of the file
given #define A 2 + 3 #define B 2 printf("%d", A * B) what does this print?
1. Given an array of n integers. Derive an array where the value of the element at index i is the product of elements in the given array except element i in the given array. The complexity should be O(n). 2. How to traverse timing graph starting from the input nodes? Data structure of the nodes in the graph is given. Write a C program for it. 3. Implement C++ hashing function.
Take a ladder with 5 steps, write a function that gives all the possible combinations of either 1,2, or 3 steps, in any order, to get to the 5th step, and returns the total number of combinations. So some of the possibilities would be [1,1,1,1,1], [1,1,1,2], [1,1,2,1], etc. Then he asked the same question with order not being considered, so [1,1,1,2] and [1,1,2,1] are the same solution.
