Given n+1 buckets with n of them with ball inside and move(a,b) function, that moves ball from bucket a to bucket b. Each ball has a different number from [1,n] on it. Move balls, so each bucket has a ball with matching number in it.

You are given an array of N elements in the form "property1: value1; property2: value2;...;propertyX: valueX;" for some some N and any X. There is also another array of M elements of the form "property: value". You are supposed to write an algorithm to remove every element in the N length array that has a "property: value" pair in the M length array. The trick is that the most intuitive solution of iterating through the M array and filtering the N array at each element is already written. You must come up with a solution that solves the problem in less than O(NM) time.
