Daily Coding Problem: Problem #636 [Medium]

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

This problem was asked by Uber.

Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand.
Find the minimum element in O(log N) time. You may assume the array does not contain duplicates.

For example, given [5, 7, 10, 3, 4], return 3.

Daily Coding Problem: Problem #637 [Easy]

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

This problem was asked by Snapchat.

Given a list of possibly overlapping intervals, return a new list of intervals where
all overlapping intervals have been merged.

The input list is not necessarily ordered in any way.

For example, given [(1, 3), (5, 8), (4, 10), (20, 25)], you 
should return [(1, 3), (4, 10), (20, 25)].

Daily Coding Problem: Problem #635 [Hard]

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

This problem was asked by Facebook.

Implement regular expression matching with the following special characters:

   - . (period) which matches any single character
   - * (asterisk) which matches zero or more of the preceding element

That is, implement a function that takes in a string and a valid regular
expression and returns whether or not the string matches the regular
expression.

For example, given the regular expression "ra." and the string "ray", your
function should return true. The same regular expression on the string
"raymond" should return false.

Given the regular expression ".*at" and the string "chat", your function
should return true. The same regular expression on the string "chats"
should return false.
