## Integers Come In All Sizes Solution

Integers in Python can be as big as the bytes in your machine's memory. There is no limit in size as there is: (c++ int) or (C++ long long int).

Integers in Python can be as big as the bytes in your machine's memory. There is no limit in size as there is:  (c++ int) or  (C++ long long int).

As we know, the result of  grows really fast with increasing .

Let's do some calculations on very large integers.

Read four numbers, a, b, c, and d, and print the result of ab + cd.

Input Format
Integers a, b, c, and d are given on four separate lines, respectively.

Constraints

Output Format
Print the result of  on one line.

Sample Input

9
29
7
27


Sample Output

4710194409608608369201743232


Note: This result is bigger than . Hence, it won't fit in the long long int of C++ or a 64-bit integer.

### Solution in Python

a,b,c,d = [int(input()) for i in range(4)]
print(a**b+c**d)
