{
int i;

Let A be a square matrix size $$n \times n$$. Consider the following pseudocode. What is the expected output?

C = 100; 
for i = 0 to n do 
for j = 1 to n do 
 { 
      Temp = A[ i ][ j ] + C ; 
      A[ i ][ j ] = A[ j ][ i ] ; 
      A[ j ][ i ] = Temp - C ; 
 } 

 for i = 0 to n do 
 for j = 1 to n do 
 output(A[ i ][ j ]);
