Given a matrix as mat[row][column], our task is to check whether the given matrix is singular or not through a function and display the result.Singular matrix is a matrix whose determinant is zero and if the determinant is not zero then the matrix is non-singular.So to find whether the matrix is singular or non-singular we need to calculate determinant first. Determinant of a matrix can be calculated as −$$M1[3][3]\:=\:\begin{bmatrix}a & b & c \d & e & f \g & h & i \end{bmatrix}$$|m1| = a(e*i - f*h) - b(d*i - f*g) + c(d*h - e*g)ExampleInput-: mat[3][3]= { 4, 10, ...
