how to pick out the diagonal elements of 5*5 matrix
Nov 1, 2020
compare the matrix with its index value matrix and figure out the index values of respective diagonal elements needed
- in the first diagonal i and j values are same (i==j)
- in the second diagonal if you closely observe , you can find … j=matrix.length - i - 1
generally we loop through this matrix rows and columns using for loop , now if you add these conditions , the requisite elements can be extracted.
Pseudocode:
Matrix=[4x4];
for loop(i ……..){
for loop(j……..){
- /include the conditions\*
if(condition 1 for diagonal 1)
push the matrix[i][j] in to an array
if(condition 2 for diagonal 2)
push the matrix[i][j] in to an another array
}
}
the end
