11. It is known that ABC is a three digit number, and the sum of the other five three digits composed of a, B and C is 2006, The sum of the other five three digits composed of a, B and C is 2006, so the difference between the largest and the smallest of the six three digits is
12. With the 10 numbers from 0 to 9, you can make up the even number of three digits without repetition 1. When the mantissa is 2, 4, 6 and 8, the number of bits combined is 4. Because the hundreds cannot be 0, the number of bits combined is 8, and the number of bits combined is 8 × 8 × 4 = 256 2. When the mantissa is 0, the combination of 100 bits is 9, the combination of 10 bits is 8, and the total number of combinations is 9 × 8 × 1 = 72 Total 256 + 72 = 328 On the basis of this classification, I have a question: why should we take the hundred first, if we take the ten first. Process 1: there are 9 combinations of ten (ten can take 0), and 7 combinations of hundred
