Daily Coding Problem #2

# Problem 2

This problem was asked by Uber.

Given an array of integers, return a new array such that each element at index i of the new array is the product of all the numbers in the original array except the one at i.

For example, if our input was [1, 2, 3, 4, 5], the expected output would be [120, 60, 40, 30, 24]. If our input was [3, 2, 1], the expected output would be [2, 3, 6].

Follow-up: what if you can't use division?

Daily Coding Problem #1

Problem 1

Given a list of numbers, return whether any two sums to k. For example, given [10, 15, 3, 7] and k of 17, return true since 10 + 7 is 17.

Bonus: Can you do this in one pass?

Amazon Interview Islands Question (Daily Coding Problem)

Good morning! Here's your coding interview problem for today.

This problem was asked by Amazon.

Given a matrix of 1s and 0s, return the number of "islands" in the matrix. A 1 represents land and 0 represents water, so an island is a group of 1s that are neighboring whose perimeter is surrounded by water.

For example, this matrix has 4 islands.
