STEP1 : Arrange 10 distinct digits and 2 blank spaces into 3x4 matrix.

Example:

1	2	sp	8
4	5	6	7
3	sp	0	9

STEP2 : Now sum up the numbers row by row (in our example SumRows=12+8+4567+3+9=4599).

STEP3 : Next sum up the numbers column by column (in our example SumCols=143+25+60+879=1107).

STEP4 : Evaluate the ratio R= (bigger sum)/ (smaller sum). In our example 4599/1107=4.14543

You are requested to arrange the 12 symbols so that the value of R will be as close as possible to:
a) 1.000
b) 2.000
c) Phi (the golden ratio =1.618034)
