Theme: Middle Number Syndrome

Author/Opus: This is the 101st puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Sudoku rules: Insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region. Also, each clue given outside the grid must appear somewhere in the first three cells in the corresponding direction. This clue represents the median (i.e., middle value) of those three cells. (For example, the clue to the top of column 2 indicates that in R123C2 one of the three cells is lower than 4, one is 4, and one is higher than 4.)
