- A 3rd grade math problem with huge number of answers
- It take very long time if process with usual way
- Use algorithm to optimize process speed, the result of total time less than 1 second
- Recorded in the top 1 of the python class history record
- Calculating the number of solutions to the 3rd grade math problem
- With variables a,b,c,d,e,f,g,h,i being numbers in the range 1-9 (variables with can have the same value), the expression:
a + 13 * b / c + d + 12 * e - f - 11 + g * h / i - 10 = 66
