Take three different numbers from 1,3,5,7,9, and then take two different numbers from 0,2,4,6,8, to form five digits larger than 70123. How many are there

Take three different numbers from 1,3,5,7,9, and then take two different numbers from 0,2,4,6,8, to form five digits larger than 70123. How many are there

Since the last four digits of 70123 are the minimum number composed of the smallest four digits in 0-9, that is to say, if you take any four digits in 0-9, it will be greater than or equal to 0123, so as long as the first digit is greater than or equal to 7, it will meet the requirements
When the first digit is 7, the last four digits should be 2 from 1,3,5,9 and 0,2,4,6,8, with a total of 6 * 10 = 60;
The last four digits are sorted out, and each sort generates a number. A total of 60 * 4 * 3 * 2 = 1440 numbers are generated, but 70123 is unqualified, which needs to be removed, and finally 1339 numbers are generated
When the first digit is 9, as above, 1440 numbers are generated
When the first digit is 8, three of the last four digits should be taken from 1, 3, 5, 7 and 9, and then one from 0, 2, 4 and 6, with a total of 10 * 4 = 40;
Finally, 40 * 4 * 3 * 2 = 960
The total number is 1339 + 1440 + 960 = 3839
