Determinant of a matrix gfg
WebMar 12, 2024 · I am trying to calculate the determinant of a Matrix recursevily. The function I wrote does not take any parametres (because its a function in a class, so the matrix is defined by the "this->" command). So the minimum case I guess it is when a matrix 2x2 can be solved. In this case, in a matrix 3x3, it would be solved by multipling the 1st ... WebBoolean Matrix. Given a boolean matrix of size RxC where each cell contains either 0 or 1, modify it such that if a matrix cell matrix [i] [j] is 1 then all the cells in its ith row and jth column will become 1. Input: R = 2, C = 2 matrix [] [] = { {1, 0}, {0, 0}} Output: 1 1 1 0 Explanation: Only cell that has 1 is at (0,0) so all cells in row ...
