Given the function signatures

Multiplication- int multiplication(int a,int b)

Area of the circle- float circle_area(int radius)

Check if the number is even or odd- void iseven(int number)

Find factorial- int fact(int n)

Smallest of 3 number- int smallest(int a,int b, int c)

Read the choice where , if choice is 1 Multiplication should be performed, if choice is 2 Area of Circle should be executed, if choice is 3 them it has to execute the function of checking number is even or odd, if the choice is 4 then it has to find the factorial of a number and if the choice is 5 then execute the function smallest of 3 numbers

Wedding Game

In a wedding that you are attending, there are some chairs that have digits inscribed at their

backs. The chairs are lined in a row such that they form a string of the digits. Find the

minimum number of sets M that can be formed from these digits such that:

1. The number of digits in each set is one or more than one.

2. Each set is formed using consecutive digits and no digit can be used more than once.

3. In each set, the number formed using the digits is less than or equal to Y.

Input Specification:

input1: S, string of digits

input2: Y, No number should be greater than Y

input3: Size of the String S

Output Specification:

Your function should return M, the minimum number of sets

Example 1:

An E-Commerce commerce company plans to give their customers a discount for the New Years holiday. The discount will be calculated based on the bill amount of the order placed. The discount amount is the product of the sum of all odd digits and the sum of even digits of the customer’s total bill amount. If no odd digit is present in the bill amount, then 0 will be consider for its corresponding sum.

Write an algorithm to find the discount amount for the given total bill amount.
