I have an array like this in the array,
uint256[] public numberArr= [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
Each number in an array have their own weight,
uint256[] public weightNumberArr = [1, 3, 9, 7, 15, 18, 36, 22, 12, 6];
Here you can say that the weight of number 0 is 1 and for number 2 it is 3 like that. So here Chance of arriving number 6 is more than a chance of arriving number 0.
How can I generate a random number array of 0 to 9 by using weighted probability in solidity?
Any help will be highly appreciated!
