The second line consists of N separated integers - temp1, temp2... temp N-1. Write an algorithm to help the company prepare the list of temperatures that are not included in the range min to max.
10. Keys - Given three numbers, write an algorithm to find the key using the mentioned formula. Formula: key = [SMALLEST digit in the thousands place of all three numbers][LARGEST digit in the hundreds place of all three numbers][SMALLEST digit in the tens place of all three numbers][LARGEST digit in the units place of all three numbers]
11. Online Maths Tutorial - In an online maths tutorial a student is given a list of N numbers. Print N space-separated integers representing the sum of each element in the list.
12. Unique authors - An online book reading community's grid displays books in a specific format. Write an algorithm to help the community find the count of unique author's initials present in the given batch of books.
13. Pipes - Andrew manages a pipe warehouse. He wishes to automate the process of transferring the pipes from the warehouse to the carrier truck. There are N pipes in the warehouse. In the automated system, a drone picks the pipes by length and carries them to the carrier truck. In each turn, the drone moves from left to right to find the pipes whose lengths are greater than the pipe on their left. The drone repeats this process until it has no more pipes to pick. Write an algorithm to output the list of pipes that will remain in the warehouse after the drone has completed this process.
14. Oil Factory - An oil factory has N number of containers and each has a different capacity. During renovation, the managerwishes to make different pairs for the containers in such a way that in the the first pair, the container of maximum capacity is paired with the container of minimum capacity, and so on for the rest of the containers. Write an algorithm to make different pairs of containers in such a way that the first container in the pair is of maximum capacity and second container in the pair is of minimum capacity.
15. Toys Fun - The children's toy making company "ToysFun" is building cubic shaped learning toys. Write an algorithm to help the toy manufacturers find the total count of perfect cube numbers present in the list of dimensions.
16. Save Earth - The NGO SaveEarth is planting trees on a straight highway road. For this purpose, they have divided the road into virtual blocks. The NGO will plant the trees over the course of two days. The first block will be plowed on the first day and the second block will be plowed on the second day, third block on first day and so on. Write an algorithm to find the total fertility value of the blocks plowed on first day.
