Place the letters A to J, one per square, so that no two consecutive letters in alphabetical order are in squares that touch in any way, even at a corner. Three letters have been placed to get you started.
Solution to the Problem:
The letters B and D cannot be placed next to the letter C, so they must be placed in the top square and the first square in row three. But the letter D cannot be placed next to E, so D must be in the top square and B must be between H and E.
