The code needs to be written in a Simulator Teaching Language like the code below but the output of my code is wrong. I will need help to debug and fix it in order to output the right matrix multiplication of A$*$A

program MatrixMultiplySerial

$$ regvar matrixSize integer $=8$

$$ var matrixA array$(64)$integer

$$ var matrixResult array$(64)$integer

$$ regvar i integer

$$ regvar j integer

$$ regvar k integer

$$ regvar sum integer

$$ regvar row$1$integer

$$ regvar col$2$integer

$$ regvar resultIdx integer

$$ for i $=0$to $63$

$$ matrixA$[$i$]=$i $+1$

$$ matrixResult$[$i$]=0$

$$ next

$$ for i $=0$to $7$

$$ for j $=0$to $7$

$$ sum $=0$

$$ resultIdx $=$i $*8+$j

$$ for k $=0$to $7$

$$ row$1=$i $*8+$k

$$ col$2=$k $*8+$j

$$ sum $=$sum $+($matrixA$[$row$1]*$matrixA$[$col$2])$

$$ next

$$ matrixResult$[$resultIdx$]=$sum

$$ next

$$ next

$$ writeln$("$Matrix Multiplication Result:"$)$

$$ for i $=0$to $7$

$$ for j $=0$to $7$

$$ write$($matrixResult$[$i $*8+$j$],"")$

$$ next

$$ writeln

$$ next

end
