Problem 1: Given the API rand7 () that generates a uniform random integer in the range [1, 7], write a function rand10() that generates a uniform random integer in the range [1, 10] . You can only call the API rand7(), and you shouldn't call any other API. Please do not use a language's built-in random API.

Write a C program that compute the perimeter of Circle, Rectangle, Triangle and Square. The program asks the user to specify the shape as follows: C for Circle, S for Square, R for Rectangle and T for Triangle and then it reads the required value to compute the perimeter for that specified shape. Note: the perimeter for the shapes:????l? = ? ×ばつ ?????? ×ばつ ?S????? = ? ×ばつ ????????????? = ? ×ばつ (????? + ??????) ???????? = ????? + ????? + ????3

Print grid pattern in python

Create a program in python with a main function and a custom module named rect that defines three custom functions about rectangles as follows: a value-returning function that takes a rectangle's dimensions as parameters and returns the perimeter. a void function that takes a rectangle's dimensions as parameters and prints the area. a value-returning function that takes a rectangle's dimensions as parameters and returns the diagonal length. In the main function, import your custom module, prompt the user for the dimensions of a rectangle, and then use all three module functions. Duplicate the display of decimals shown in the Sample Output.
