B is the perfect number.Analysis:X + 2 = (A + 2) * (b + 2)Because X1=1,x2=3. All the numbers are derived from two numbers. Then we canTo draw a conclusion. A number x hypothesis is the perfect number. so x = 3^p*5^q;So the code is as follows:#include can also play the table to the 1E9 within the total number of perfect num
