I am what you call a perfectionist. I always strive for perfection, and I appreciate everyone and everything that is perfect. That is why I have recently acquired an appreciation for perfect numbers! I absolutely need to know which numbers from 1 to 1000 are considered perfect. From what I recall, a perfect number is a positive integer that is equal to the sum of all its divisors other than itself. Example: 6 is a perfect number because the divisors of 6 other than itself are 1, 2, and 3, and 1 + 2 + 3 = 6. c++ code

Transcribed Image Text 2-a) A lightning strike on the fell on Jonathan's house and destroyed the whole house. Now he decided to build a new house and he is now choosing a location where he wanted to build it. Assume the whole area be of rectangular field of size NxM. The mayor did not let Jonathan's build the house on the places where the lightning strike. The mayor said that some of the cells of the field are dangerous for the foundation. There are exactly K such cells. The house will occupy a rectangular area in this stripe with sides parallel to the sides of the original site. Your task is to help Jonathan for finding each Li, H; (the lowest and the highest boundaries). Create a simple JAVA program that finds the maximum area of the house that Jonathan can build on the relevant site.

Correct answer will be upvoted else Multiple Downvoted. Computer science. Athenaeus has recently wrapped up making his most recent melodic piece and will introduce it tomorrow to individuals of Athens. Tragically, the tune is somewhat dull and almost certain will not be met with a warm gathering. His tune comprises of n notes, which we will treat as certain integers. The variety of a tune is the number of various notes it contains. As a supporter of music, Euterpe looks after arrangers and guides them all through the method involved with making new tunes. She chose to help Athenaeus by changing his melody to make it more assorted. Being a minor goddess, she can't self-assertively change the tune. All things being equal, for every one of the n notes in the tune, she can either leave it for what it's worth or increment it by 1. Given the tune as an arrangement of integers portraying the notes, discover the maximal, attainable variety. Input The input comprises of numerous…
