I cannot reveal the questions I got asked. But here's some that has very similar flavor: 1) Check if an integer is a palindrome (do not convert the integer to string) 2) Given 2 sorted arrays of integers, code to find a number from each array such that their sum are closest to some integer K? 3) What is the degree of freedom for lasso?
Why is the sum of squares error used?
You have a function which gets k as input and in o(1) time returns a random number between 1 to k. Create a function that returns a random permutation (a list of the numbers 1 to n in a random order), optimize for speed (I think O(n) is best).
