Victor has an array of size n. He loves to play with these n numbers. Each time he plays

with them, he picks up any two consecutive numbers and adds them. On adding both the

numbers, it costs him k*(sum of both numbers).

Find the minimum cost of adding all the numbers in the array.

Input Specification:

input1: Size of array.

input2: Elements of the array.

input3: Value of k.

Output Specification:

Return the minimum cost of adding all the numbers of the array.

Trapezium Order

you are given an integer N . print N rows starting from 1 in the trapexium order as shown in the output of the below examples .

Input

the input contains an integer N

OUTPUT

the output should have N lines

each of the N lines should have space -seperated integers as per the trapezium order

Develop a C++ code for a function that takes the GPA of students from the user; this function should work for different class sizes specified by the user (class size may be 30, 40 or 50). Function should display the GPA of those students who has GPA more than 3.5.

Suppose we have 999 records of employees Emp1, Emp2, Emp5, Emp6 and so on up to Emp998 and Emp999 stored in a sequence. Hence, records are nothing but a row in the table. In the employee table, we want to insert new records Emp3 and Emp4 in the sequence, and once we have done insertion we need to update and retrieve the record efficiently to optimize the performance of a database by minimizing the access time when query is being executed.

You are required to solve the problem with the index sequential access method with pros and cons in the given scenario.

Suppose a company “ABC” is conducting a test to hire you as OOP Developer and asked you develop a calculator for the basic Arithmetic operators (+, -, *, /, %), where you have to deal at least 11 digit numbers. The numbers can be of with decimal point or without decimal point. The company wants you to develop an efficient code. You can choose any of the following options to develop this whole scenario:

•       Function Overloading            
•      Class Template

You have to answer, which option will you choose and arguments in favour of your chosen option regarding code efficiency, code complexity and other factors.

For Apple store services and apps(like games, videos, etc ): you can gain access if you are15years old or less and your parent has an Apple ID. If you are 16 years old or more you need to have your own Apple ID.

Write a program that uses short circuit logic to tell someone if they are legal to gain access to Apple store services. First ask them how old they are, whether they have an Apple ID or not, and whether their parent has an Apple ID or not.

The sum of the first n positive integers can be computed by the formula

sum(1..n) = 1 + 2 + 3 + 4 + · · · + n = n(n + 1)/2

Write a short Python program that computes the sum of the first 100 positive integers and prints it to the screen, using format specifiers when printing instead of converting each item to a string. Use variables to represent the 1, the 100, and the result of the computation. Your program must compute the 5050 value. You cannot just print the result to the screen. You must compute it first from the 100. The goal is for the output to look exactly the same.The output is as shown below:

sum(1..100) = 5050
