Please use ide.geeksforgeeks.org, generate link and share the link here. Approach :To get the reverse wave form for a given matrix, we first print the elements of the last column of the matrix in downward direction then print the elements of the 2nd last column in the upward direction, then print the elements in third last column in downward direction and so on. Here we are using two different tricky methods that how to reverse a two-dimensional array in python. There are various ways to reverse an array. On the left you make permutations of rows. B = fliplr(A) returns A with its columns flipped in the left-right direction (that is, about a vertical axis).If A is a row vector, then fliplr(A) returns a vector of the same length with the order of its elements reversed. However, you can make Arrays change its size Dynamically by using Dynamic Memory Allocation techniques with Pointers. // i, j - Iterator.

Today Microsoft released Power BI Desktop March 2020 which I was hoping that it includes a simple feature on Matrix visual to be able to sort the Martix by column in descending order, but, it doesn’t. It is important that we should know How A For Loop Works before getting further with the C Program Code. The simplest form of multidimensional array is the two-dimensional array. int row1, row2; cout << "Enter the size of matrix : "; cin >> m>> n; int ** matrix = new int* [n]; // initialising columns for each row. C Program To Reverse a String using Stack. The first function, reverse_row() is called in a loop on the rows of the 2d array with odd indices, then the transpose_array() function is called on the resulting array. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. C program to reverse an array using an additional array, using swapping and by using a function.For example, if 'A' is an array of integers with three elements such that, A = 1, A = 2, A = 3 C Reverse an Array.
