find the sum of greater 6 digit number and smallest 7 digit number statement
Answers
The idea is to pick the smallest possible 1st digit that will permit the number to have different digits. Then we pick the smallest possible 2nd digit that will permit the number to have different digits, and so on until we have picked all 7 digits.
The smallest first digit we can pick is 1. We can't pick 0 since it wouldn't have 7 digits. The smallest 2nd digit we can pick is 0. We have now 5 more digits to pick that all are different .
The smallest 3rd digit we can pick is 2. We have now 4 more digits to pick . The smallest 4th digit we can pick is 3. Now we can pick 3 different digits. The smallest 5th digit we can pick is 4.
We only need to pick 2 more different digits. The smallest 6th digit we can pick is 5. We have picked all different digits, and have 1 more digit to pick. The smallest 7th and last digit we can pick is 6.
