Hello everyone, please I need help with this code.

Inside the following loop, I want to create three empty integer arrays to save the value of f, x and y inside it. I want the arrays are unknown size because my code uses to generate random samples from distributions, in the `f=rpois(1,4)`

I generate one value from Poisson distribution if the value from this command is (1) so, in `x = rexp(f,1/2)`

I will generate one value from exponential distribution and in `y= rexp(f,1/4)`

I will generate one value from exponential distribution but if the result from this `f=rpois(1,4)`

command is (2) so I will generate two values from x and two values from y and so on. So the size of x and y arrays depends on the value of f and f is random (if f is 3 then x are 3 values and y are 3 values if f is 4 then x are 4 values and y are 4 values ....).

```
count=0
for (j in 1:10000000)
{
f = rpois(1,4)
if(f == 0)
{
count = count + 1
next
}
xx = rexp(f,1/2)
yy = rexp(f,1/4)
}
```

Please help.

Thank you in advance,
