When defining a Java array, the index range of the array: O Must start at 1 O Must start at o Can be a customized range (from 2 to 5, e.g.) at compillation time Can be a customized range (from 2 to 5, e.g.) at run time

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]]

In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise.  A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks.  Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…

in c++  using 2D Arrays The following diagram represents an island with dry land (represented by “-“) surrounded by water ((represented by “#“). ##-########## #-----------# #-----------# #------------ # -----------# #------X----# #-----------# ############# Two bridges lead off the island. A mouse (represented by “X”) is placed on the indicated square. Write a program to make the mouse take a walk across the island. The mouse is allowed to travel one square at a time, either horizontally or vertically. A random number from 1 to 4 should be used to decide which direction the mouse is to take; for the sake of uniformity assume that 1 = up, 2 = down, 3 = left, and 4 = right.  Since the mouse is wearing cement mouse galoshes, the mouse drowns when he hits the water. He escapes when he steps on a bridge. You may generate a random number up to 100 times allowing the mouse to take 100 steps. If the mouse does not find a bridge by the 100th try, he will wither away and die of starvation.…
