Question

Write a script called FindFactorial.m to do the following:- Ask user to input an integer (k)- Find the smallest integer (n) for which the factorial n! is greater than k
Your script can have just one loop and you may NOT use MATLAB built-in function to calculate factorial.Run your script for k = 123456 and find the result.

Answer 1

How about this:
```python
k = input('Please enter an integer k:');
n = 0;
n_factorial = 1;

while n_factorial <= k
n = n + 1;
n_factorial = n_factorial * n;
end

fprintf('%d! > %d\r\n', n, k);
fprintf('%d! = %d\r\n', n, n_factorial);
```
