Bhushan Bhasme · Answer

int[][] arr = new int [4];
Here You Are Taking Mulidiamensional array but You are Not column size
int [,] array2D = new int [,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } }; // The same array with dimensions specified.
int [,] array2Da = new int [4, 2] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };
if You dont want to specify Column size then You can Do it Like
int [][] arr = new int [3][];(Jagged Array:column size Is Not Fixed)
