Resampling

Resampling

Suppose that you have 5 particles, each with an importance weight. Compute the probability of drawing each particle in the new set. Use the C++ coding section and follow the instructions to print the results.

#include <iostream>

using namespace std;

double w[] = { 0.6, 1.2, 2.4, 0.6, 1.2 };//You can also change this to a vector

//TODO: Define a  ComputeProb function and compute the Probabilities







int main()
{
    //TODO: Print Probabilites each on a single line:
