The program must read its input from standard input (stdin) and write ONLY the required answer to standard output (stdout).\nThen TEST it against the example cases shown in the problem: run your program on each example input with bash, e.g. `printf '<example input>' | python3 solution.py`, and compare its output to the expected output. If an example fails or the program errors, use the `edit` tool to fix `solution.py`, then run it again. Keep going until your program passes all the provided examples, then stop.\n\nPROBLEM:\nGiven an integer a as input, print the value a + a^2 + a^3.\n\n-----Constraints-----\n - 1 \\leq a \\leq 10\n - a is an integer.\n\n-----Input-----\nInput is given from Standard Input in the following format:\na\n\n-----Output-----\nPrint the value a + a^2 + a^3 as an integer.\n\n-----Sample Input-----\n2\n\n-----Sample Output-----\n14\n\nWhen a = 2, we have a + a^2 + a^3 = 2 + 2^2 + 2^3 = 2 + 4 + 8 = 14.\nPrint the answer as an input. Outputs such as 14.0 will be judged as incorrect."
