1. Write a function that would approximate the Euler's number e. The function takes the one value k, and the output is the approximation value. n=0 2. Using a for loop, calculate the value of the approximation from k=1 through 50 and store it to the vector. 3. Using a while loop to find the value n where the difference between the true value e and the approximation is less than 0.00001. 4. Using the while loop in #3, create a function for approximating e. The input is the desired absolute difference, and it returns the n. Try the function using 0.0001
