Explain Elimination of common sub expression during code optimization
An optimizing transformation is a regulation for rewriting a segment of a program to enhance its execution competence without influencing its meaning. One of the methods is "Common sub expression elimination"
In given expression as "(a+b)-(a+b)/4", in this "common sub-expression" termed to the duplicated "(a+b)". Compilers implementing such technique realize that "(a+b)" won't modify, and as such, only compute its value once.
Illustrate what is pascal's principle? Answer:- Pascal's Principle declares that the pressure is transmitted evenly through a liquid. That's why when you pump up a balloon
The NOR gate. The NOR gate is equivalent to an OR gate followed by a NOT gate so that the output is at logic level 0 when any of the inputs are high otherwise it is at logic le
