Problem Statement  
You are given several colored bricks. Every face of each brick has some color. Only seven colors are used.

Return the minimum number of faces that must be repainted for all the bricks to be equal. You are given a String[] bricks, each element of which represents a single brick. Each brick is represented as a 6 character string containing the colors of the 6 faces in the following order: front, right, back, left, top and bottom. The digits '0' through '6' are used to denote the seven colors.
