(De Morgan’s Laws)In this chapter, we discussed the logical operators &&, ||, and !. De Morgan’s Laws can sometimes make it more convenient for us to express a logical expression. These laws state that the expression !(condition1 && condition2) is logically equivalent to the expression (!condition1 || !condition2). Also, the expression !(condition1 || condition2) is logically equivalent to the expression (!condition1 && !condition2). Use De Morgan’s Laws to write equivalent expressions for each of the following, and then write a program to show that both the original expression and the new expression in each case are equivalent.
a) !( x<5 ) && !( y >= 7 )b) !( a == b ) || !( g != 5 )c) !( ( x <= 8 ) && ( y > 4 ) )d) !( ( i > 4 ) || ( j <= 6 ) )
