#include <iostream>
#include <vector>
#include <limits>

double findMaxValue(const std::vector<std::vector<double>>& array) {
    double maxValue = std::numeric_limits<double>::lowest(); // Initialize to the smallest possible value

    // Traverse the multidimensional array
    for (const auto& subArray : array) {
        for (const auto& value : subArray) {
            if (value > maxValue) {
                maxValue = value; // Update maxValue if a larger value is found
            }
        }
    }

    return maxValue;
}

int main() {
    // Define a multidimensional array
    std::vector<std::vector<double>> arr = {
        {1, 2,  3.14},
        {1, 1, 16.80},
        {3, 5, 17.50},
        {2, 4, 11.03}
    };

    double maxValue = findMaxValue(arr);
    
    std::cout << "The maximum value in the array is: " << maxValue << "\n";

    return 0;
}


/*
run:

The maximum value in the array is: 17.5

*/
