In an OR decision, why is it more efficient to first ask the question that is more likely to be true?

What will be an ideal response?


The general rule is: In an OR decision, first evaluate the condition that is more likely to be true. This approach eliminates as many executions of the second decision as possible, and the time it takes to process all the data is decreased. As with the AND situation, in an OR situation, it is more efficient to eliminate as many extra decisions as possible.
