PLEASE USE C PROGRAMMING TO CODE THIS PROBLEM. EXPLAIN the logic with us of a diagram if possible, or clear enough that i can write this code if I was to ever come across a problem like it again Description Given a board with N rows and M columns, the rows are numbered from 1 to N from top to bottom, and the columns are numbered from 1 to M from left to right. Each element has one diagonal wall which either runs from top-left corner to bottom-right corner, or runs from top-right corner to bottom-left corner. Now given Q queries, you have to output which column the ball will fall out at the bottom row if you put it on top of the board at specific column. (The ball will naturally fall down due to gravity.) The following figure is a sample. If you drop the ball at column 2, the ball will fall out at the left side. If you drop the ball at column 5, the ball will be stuck in the board. If you drop the ball at column 3, the ball will eventually fall out at column 2. Input First line…
C programming You will be given a 3x3 matrix as input. You need to check whether the matrix is a magic square or not. Magic squares are the matrices which have equal sum along all rows, columns and diagonals. For example, This is a magic square as you can see all the sums are equal to 15 along all the rows and columns and even the diagonals. Now,Write a C Program to check the matrix is magic square or not. 2 7 6 9 8 1 4 3 5 NO 2 7 6 9 5 1 4 3 8 YES
Note: Please answer in C++ Programming language. During Eid, it is a tradition for every father to give his children money to spend on entertainment. Chef has N coins; denote the value of the coin i by vi. Since today is Eid, Chef gives one coin to each of his two children. He wants the absolute value of the difference between the values of the coins given to the two children to be as small as possible to be as fair as possible. Help the chef by telling him the minimum possible difference between the values of the coins given to the two children. Of course, the chef cannot give the same coin to both children.

please help, make the diagram very clear and make sure to use c++ terminology please. if possiible could you make the diagram handwritten :) Fish have different species, sizes, colours and favourite foods. They can swim, `blub`, and attempt to eat food (which can be successful or not—depending on what it is). Fish live in aquariums that are of particular volumes and shapes. Aquariums have different kinds of lights, gravel, and filtration technology. Fish can also fight with one another… it is all very exciting. Create class diagrams for the candidate entities in the above paragraph. You can do the UML ascii art style or submit physically.
