circles puzzle
We have the numbers 1,2,3,4,5,6,7.
And we have seven circles connected together by straight lines as shown in the figure.
What is required is to distribute the numbers from 1 to 7 in circles, provided that the difference between the two numbers connected by the straight line must be greater than 1. For example, if 4 and 5 are connected in a straight line, this is wrong because 5 - 4 = 1, the difference must be greater than one.
