+finding tanspose of the given matrix
+The transpose of a matrix is a new matrix formed by 
+flipping the original matrix over its main diagonal, 
+effectively interchanging its rows and columns
+suppose A=[[1,2,3],
+           [4,5,6],
+           [7,8,9]]
+           is the given matix then it's transpose will be
+        A^t=[[1,4,7],
+             [2,5,8],
+             [3,6,9]]
+Apporoach:
+1. Create a empty(null) matrix of the same size of the given matrix
+2.traverse the given matrix by using nested for loop
+3.copy the elements in oppposite order of the traversl
+i.e. trans[j][i]=matrix[i][j]
+"""
