![]() Traverse the given 2D vector and updated the value at the current cell with the value stored in Pos and Neg array.Sort both the Array of Vectors increasing order.Store the diagonal element with the negative difference in another Array of Vectors(say Neg) such that elements at the cell having difference(say -b) is stored at index abs(-b) = b of Neg array.Store the diagonal element with a positive difference in one Array of Vectors(say Pos) such that elements at the cell having difference(say a) is stored at index an of Pos array.The cells having the same difference from top-left to bottom-down cell forms a diagonal.īelow are the steps to sort diagonal in decreasing order: The above images show the difference between the column index and row index at each cell.

The array consists of data of any data type. An array is a group of homogeneous data items which has a common name. An array is one of the data types in java. Some of the functions associated with a 2D vector: size(): Returns the number of elements in the 2D vector. The following article, 2D Arrays in Java, provides an outline for the creation of 2D arrays in java. It is the same as a matrix implemented with the help of vectors. ![]() Maximum size square sub-matrix with all 1s What is 2D vector In C++, a 2D vector is a vector of vectors which means that each element of a 2D vector is a vector itself.Search in a row wise and column wise sorted matrix.Count all possible paths from top left to bottom right of a mXn matrix.Inplace rotate square matrix by 90 degrees | Set 1.Find the number of islands | Set 1 (Using DFS).Program to find largest element in an array.ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.
