Tower Defense (917)

Instruction:
Place a number from 1 to X (integers only) into each cell so that each number appears exactly once in each row and column. (X is the number of cells in each row.) A cell with an uncircled number "attacks" (up to) four other cells that are at an orthogonal distance equal to that uncircled number. A cell with a circled number does not attack, but must be attacked by at least as many cells as its number. Some numbers may be given to you.
