Thousands *** 14 is not equal to 24, and thousands * * 1000 is less than 20 14. The sum of the last three digits must be equal to 23. If there are two 9s in the last three digits, it is1995,65438. If there is 9, the last three digits can be composed of 6, 8 and 9 ***6; Can be composed of 7, 7 and 9 ***3; If there is no 9, it can only be composed of 8, 8 and 7 ***3.
So * * * has 3+6+3+3= 15.
