1.)
<span>((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) </span>
<span>The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. </span>
<span>For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. </span>
<span>a.) (i <= n) || (i >= n) </span>
<span>This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. </span>
<span>b.) (a[i] == 0) && (a[i-1] == 0) </span>
<span>This means that both of these terms are true. We substitute. </span>
<span>((i <= n) && true) || (((i >= n) && true)) </span>
<span>Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: </span>
<span>(i <= n) || (i >= n) </span>
<span>This is clearly always true. </span>
Answer: C. Semantic Search Engines
Explanation:
Semantic search is simply search with meaning. It is designed to locate information based on the nature and meaning of Web content, not simple keyword matches (like in lexical searches)
Answer:
A: shift in user's role from the passive consumer of content to its creator
Explanation:
During the phase of Web 2.0, consumers evolved from just been highly informed and socially connected (in other words, they evolved from being just passive consumers) to a more engaged and empowered consumer. This implied that consumers could easily adapt to new technologies to meet individual needs and create an emotional bond with brands. They evolved from passive consumers to being the creators of what they wanted to meet their specific needs.
I would say the answer is b, but ⟟ might be wrong
The answer is 1) JPEG 2) TIFF 3) BMP.
<span>The best option that should be considered when preparing these images to.be used for the web :
</span>1) JPG (jpeg) - Used to compress web images to a small file size without
sacrificing quality
2) TIFF (tiff) - Used for professional print images to save in a uncompressed
file format at high resolution.
3) BMP - Used for either web or print because of the ability to save high
quality images ether compressed or uncompressed.
