As I am building the e-commerce app for the other startup, I ran into a problem where I had to filter an array of objects in an Observable (Angular). Obvservable as in one of the RxJS operators. The problem was Read more
My solution to a “Daily Coding Problem” that I received in my mail today. You are given an array of length n + 1 whose elements belong to the set {1, 2, …, n}. By the pigeonhole principle, there must be a duplicate. Read more
My solution to a “Daily Coding Problem” that I received in my mail today. Given a string, determine whether any permutation of it is a palindrome. For example, carrace should return true, since it can be rearranged to form racecar, which is a Read more
My solution to a “Daily Coding Problem” that I received in my mail today. Implement integer exponentiation. That is, implement the pow(x, y) function, where x and y are integers and returns x^y. Do this faster than the naive method of repeated multiplication. For example, pow(2, 10) should return Read more
My solution to a “Daily Coding Problem” that I received in my mail today. Given a list of elements, find the majority element, which appears more than half the time (> floor(len(lst) / 2.0)). You can assume that such element Read more
My solution to a “Daily Coding Problem” that I received in my mail today. Given a multiset of integers, return whether it can be partitioned into two subsets whose sums are the same. For example, given the multiset {15, 5, 20, Read more
My solution to a “Daily Coding Problem” that I received in my mail today. Given a 2-D matrix representing an image, a location of a pixel in the screen and a color C, replace the color of the given pixel and Read more
