Need SML help for coding. I need to define a function called decimal (val decimal = fn: string -> int) that takes a bit string corresponding to an integer and returns the decimal value of that integer. For example, decimal "10001" returns 17, decimal  "001101" returns  13.

Here is the design recipe for a Python function. def common(s1: str, s2: str) -> tuple[int, int]:    '''    Given two strings of equal length s1 and s2, return a tuple where    the first element is the number of positions where s1    and s2 have the same character, and the second element is the    number of positions where s1 and s2 have the same character ignoring case.    ''' Here are some possible test cases for this function. Assume that we aregoing to include them all in our test suite, except one.Choose the letter for the test that should be removed. a) common('', '')b) common('a', 'a')c) common('aBC', 'abC')d) common('abc', '')e) common('abc', 'def')

Write a function that returns the greatest common divisor of 2 integers.

Write a C++ function factorial that takes an integer, n, and returns the value of n factorial (a.k.a., n!): When n is positive, n! = 1 * 2 * 3 * ... * n.  For example, 5! = 1 * 2 * 3 * 4 * 5 = 120. When n is zero, n! is defined to be 1. When n is negative, n! is undefined. You may assume that the parameter n will not be negative for this problem.

Write a python function that takes two very large integers as input and returns their sum. You can only use plain Python and no Bignum data types.

use c code to Develop a function that gets two same length strings as parameters and reports the number of characters that they have different. For example, if the two strings are   Str1: “Hello world! Happy Friday”Str2: “Hello Johny! happy friday”   The function should return: Your strings are different in 7 places However, if the strings are exactly equal, it should just say Your strings are the same   If the strings are not of the same length, the code should just say: The two strings are not of the same length!   Hint: 1.compare the two strings character by character and report the differences 2.answer must have and show the output
