Write a code in C++ / cpp to solve the following problem In a hypothetical island, one can buy land in squares where the length of a square side must be a positive integer amount of meters. Buying a square of land with a side a costs a2 rhombics (a local currency). Sasha has decided to invest all of her N rhombics into the land. She can, surely, do it, buying square pieces 1 × 1 meters. At the same time she has requested to minimize the amount of pieces she buys.

Uncle let Theofanis know that a ranch is fortunate on the off chance that you can disseminate all animals in all pens so that there are no unfilled pens and there is something like one ceaseless section of pens that has precisely k animals altogether. In addition, a ranch is great in case it's fortunate for any conveyance without void pens. Neither Theofanis nor his uncle knows whether their ranch is great or not.

For any given assignment of weights to hooks, we can compute the location of the center of mass of the rod and the weights according to the following equation (neglecting the weights of the rod and the hooks). where 0 ≤ Pi≤n-1 is the position of weight along the rod.

Correct answer will upvoted else downvoted. framework of size n×m, with the end goal that every cell of it contains either 0 or 1, is considered lovely if the total in each adjoining submatrix of size 2×2 is actually 2, i. e. each "square" of size 2×2 contains precisely two 1's and precisely two 0's. You are given a network of size n×m. At first every cell of this network is unfilled. How about we indicate the cell on the crossing point of the x-th line and the y-th segment as (x,y). You need to handle the inquiries of three sorts: x y −1 — clear the cell (x,y), in case there was a number in it; x y 0 — compose the number 0 in the cell (x,y), overwriting the number that was there already (assuming any); x y 1 — compose the number 1 in the cell (x,y), overwriting the number that was there beforehand (assuming any). After each question, print the number of ways of filling the unfilled cells of the grid so the subsequent network is delightful. Since the appropriate…

Each empty square in this grid has to befilled with a number from 1 – 9 without repeating any numbers within the row and column of thesquare. We will implement a program in C to help us solve a simple 4 ×4 Sudoko puzzle. We willinvestigate a 4 ×4 Sudoko puzzle, where each row or column is missing 2 numbers only. To fill ina square, if you scan the row (or column) of the square, you will eliminate two out of 4 numbers,and if you then scan the column (or row) of the square, you will eliminate one more number. Thus,you will be left with one missing number in the row and column of the empty square. Thus, youneed to fill in the square with this missing number. We are NOT studying the case where scanningthe row and column of a square eliminates only 2 numbers.For example, in the following grid, row 0 and column 0 is empty. If we scan row 0, we can eliminate3 and 4 since they are already there in the row. And if we scan the column, we can…Python only Rajesh loves lucky numbers.

Now this city is unlike any other city. This city is an apartment matrix and there are no roads. The only way to get around is through houses. If one of the friends passes the apartment once, the party will have to pay its full rent. From the apartment, you can go to the houses to the North, South, East, or West. Since Ramesh, Suresh, Mahesh, and Mukesh are best friends, they want to meet at least once a month. Also, all four are superstitious, so Ramesh goes West only, Suresh goes North only, Mahesh goes East only, and Mukesh goes South only. Any number of people can live in any apartment. The cost of all housing in the city is provided, some of which may be negligible. Negative costs mean that if a friend lives in or moves out of the apartment, the party will be paid an amount equal to the cost dispute.

Each player should pick one of those three advisers for be discarded. The game system then, self-assertively picks one of the aides that were not picked by any of the players and starts the game. He is significantly enthusiastic concerning the game and needs to contribute some energy focusing on maps, thusly growing freedoms to rule matches played on those aides. Regardless, he in like manner needs to finish his work, so he doesn't have the chance to focus on all of the aides.

The function in C++ you’re writing accepts an array of predicted prices for a particular stock over the course of time. For example, this array of seven prices: [10, 7, 5, 8, 11, 2, 6] predicts that a given stock will have these prices over the next seven days. (On Day 1, the stock will close at $10; on Day 2, the stock will close at $7; and so on.) Your function should calculate the greatest profit that could be made from a single “buy” transaction followed by a single “sell” transaction. In the previous example, the most money could be made if we bought the stock when it was worth $5 and sold it when it was worth $11. This yields a profit of $6 per share. Note that we could make even more money if we buy and sell multiple times, but for now, this function focuses on the most profit that could be made from just one purchase followed by one sale. Now, we could use nested loops to find the profit of every possible buy and sell…SEE MORE QUESTIONSRecommended textbooks for youDatabase System ConceptsComputer ScienceISBN:9780078022159Author:Abraham Silberschatz Professor, Henry F.
