I have successfully discovered the method to write algorithm for Collatz Conjecture and to find area using Simpson’s numerical method. But my problem is I cannot combine these program. I have trouble in storing the generated numbers under “while” loop.

**How to store the list of numbers (like 8,4,2,1) to np.array([]) such that is produces area output**

```
from __future__ import print_function
import numpy as np
from scipy.integrate import simps
from numpy import trapz
n=int(input("Enter the Number "))
count=0
a=0
a=n
while(n!=1):
if(n%2==0):
n=n//2
print(n,'\n')
count=count+1
else:
n=3*n+1
print(n,'\n')
count=count+1
y1 = np.array([n])
#This abve line should be corrected I believe
print("Collatz for ",a," count is ",count)
# Compute the area using the composite Simpson's rule.
area = simps(y1, dx=1)
print("area for Collatz",a,"=", area)
```
