Given an array of objects with a known set of properties , implement a function that finds all possible partial matches (one object's property value matches the same property on another object), and produce a results object that describes those matches in any format you want.

You are in charge of a classroom which has n seats in a single row, numbered 0 through n-1.
During the day students enter and leave the classroom for the exam.
In order to minimize the cheating, your task is to efficiently seat all incoming students.

You're given 2 types of queries: add_student(student_id) -> seat index, and remove_student(student_id) -> void.

The rules for seating the student is the following:
1) The seat must be unoccupied
2) The closest student must be as far away as possible
3) Ties can be resolved by choosing the lowest-numbered seat.

Balance a string with parentheses. "a(b)" -> "a(b)"; "(((((" -> ""; "(()())" -> "(()())"; ")ab(()" -> "ab()"; etc...

Given an NxN grid with an array of lamp coordinates. Each lamp provides illumination to every square on their x axis, every square on their y axis, and every square that lies in their diagonal (think of a Queen in chess). Given an array of query coordinates, determine whether that point is illuminated or not. The catch is when checking a query all lamps adjacent to, or on,…

You have a bunch of light bulbs. Store them as you wish. Implement a function that tells you if the light is on or off given its index and another one that toggles the state of the light bulbs given a start and end index.

There are n+1 loading docks. a permutation of boxes 1->n is placed on the first n. there is a fork that can move one box to an empty location at a time. Give an algorithm to sort then boxes with minimum number of moves.

Given a Pattern and a dictionary, print out all the strings that match the pattern.
where a character in the pattern is mapped uniquely to a character in the dictionary ( this is what i was given first).

e.g 1. ("abc" , <"cdf", "too", "hgfdt" ,"paa">) -> output = "cdf"
2. ("acc" , <"cdf", "too", "hgfdt" ,"paa">) -> output = "too", "paa"
