//Here is a modified version of the previous example that reads the previous results 
//from a JSON file and predicts the next 6 groups of numbers based on the previous results, 
//with the prediction for each group being the most common number in the previous results:

//In this modified version, the program reads the previous results from a JSON file using the 
//JSON library by nlohmann. The JSON file should contain an array of arrays, with each inner 
//array representing a group of numbers.

//The rest of the program is similar to the previous example. We define a function 'predict' that 
//takes in the 'previousResults' and returns an integer representing the predicted result for the next 
//group. The function first counts the frequency of each number in the previous results using an unordered 
//map. It then finds the number with the highest frequency and returns it as the prediction.

//In the main function, we read the previous results from the JSON file and store it in a 2D vector. We then 
//use a loop to predict the next 6 groups of numbers, and print the prediction to the console in each iteration.

// Function that predicts the next group of numbers
