Develop python program of function randomArray(m, n) that takes two integers as argument and returns a 2D m-by-n array with random elements in it. Develop python program of function adder(a1, a2) that reads two 2D arrays of the same size and returns an array that is the summation of a1 and a2. To add the two arrays, you need to add their elements, correspondingly. Develop a  python program of function inverseArray(a) that takes a 2D-array as argument and inverses the array. You will need to inverse the rows, first and then inverse the columns, next. For instance, if the array = [[2, 3, 4], [5, 6, 7]], the inverse will be = [[7, 6, 5], [4, 3, 2]]
Language: C Print a Mayo pyramid with # characters depending on user input, i.e., the pyramid height h. To this end, update the size of the array for each level of the pyramid (for each for loop passing) using the realloc function. First of all, allocate an array for the first row. You need the allocate the memory for h + 2 characters for the first row. Fill it with spaces, using the memset(row, ’ ’, h+2) command. For each row i, expand the array size to h + 4 + i, replace the last two characters of the line with # sign, followed by the string’s null terminator. That’s why you need increase the size by 2, with the respect to the original allocation, and then by 1 at each step. You also need to replace the space at the position h − 1 − i with the # character (the left slope of the pyramid). Print and examine your results, free the memory and use the valgrind function to check memory usage.
The MPI program 'Standard-Deviation.c' computes the standard deviation for an array of elements.Here, we assume that the maximum number of elements in the array is 10. Some necessary error checkings are performed to ensure that the number of inputs is correct and their values are valid.    (a) mpiexec -n 2 ./Stddev   (b) mpiexec -n 2 ./Stddev 0   (c) mpiexec -n 3 ./Stddev 7                        (d) mpiexec -n 3 ./Stddev 9         (e) mpiexec -n 4 ./Stddev 21   Standard-Deviation.c. This code is giving me an error when I compile /////////////////////////////////////////////////////////////////////////////////////////// This is an MPI program that computes the standard deviation for an array of elements.//// Note: The array is generated according to its size (the number of elements), which //       is specified by users from the command line.
