Q$/2$

WRITE A PROGRAM IN FORTRAN THAT READS THE TWO MATRICES $(3,3)$ AND $(3,3)$ B AND THEN DOES THE FOLLOWING:

$-1-$ REPLACE THE ELEMENTS OF THE FIRST COLUMN IN THE MATRIX

$(8)$ WITH THE ELEMENTS OF THE THIRD COLUMN OF THE MATRIX $($B$)$

$2-$ THE SUM OF THE ELEMENTS OF THE MAIN DIAGONAL OF THE MATRIX $($A$)$ IS CALCULATED AFTER SUBSTITUTION

$3-$ THE MATRIX $($C$)$ IS FORMED FROM THE SUM OF THE TWO MATRICES $($A$)$ AND $($B$)$ AFTER SUBSTITUTION. MAKING ANY ELEMENT IN THE MATRIX $($C$)$ WHOSE VALUE IS LESS THAN $(10)$ EQUAL TO TWICE ITS VALUE.
