Map

A map is defined as the name of a higher-order function in most of the programming languages that applies a given function to each element of a functor, such as a list, and returns a list of results in the same order. A map is also called the collection of values based on a key, i.e. a key and value pair. A map has its own set of keys. Duplicate keys are not permitted in the Map, although duplicate values are permitted. Because a Map cannot be navigated, it must be converted to a Set using the keySet() or entrySet() methods. For key-value association mapping, such as dictionaries, maps are ideal.

Question

However, our hash map is badly built, thus all values end up in the
same slot (that is, they are all in the same LinkedList). Provide an
explanation as to why doing so would undermine the goal of using a
hash map.

We have a hash map, however its construction wasn't very good since all of the values were thrown into the same bucket (that is, they are all in the same LinkedList). If this is the case, please explain why it would be ineffective to use a hash map in the first place given the circumstances.
All the values were thrown into the same hash bucket, therefore the hash map isn't particularly good (that is, they are all in the same LinkedList). If this is the case, please elaborate on how using a hash map in the first place will be rendered ineffective.
We have a hash map that was not formed very well, and all of the values have been put in the same bucket (that is, they are all in the same LinkedList). Explain why this violates the objective of using a hash map in the first place.
However, our hash map was poorly constructed, so all of the values are now in the same pile (that is, they are all in the same LinkedList). To what extent does this defeat the purpose of a hash map, please explain.
As a result of having all the data in one place, our hash map is not particularly well-created (that is, they are all in the same LinkedList). If so, please elaborate on how this defeats the use of a hash map.
We have a hash map that wasn't made very well since all the values were dumped into the same bucket (that is, they are all in the same LinkedList). Explain why employing a hash map in the first place would be defeated by this, if that is the case.
We have a hash map that was not constructed correctly since all of the values were placed into the same bucket (that is, they are all in the same LinkedList). Give an explanation of how this negates the objective of utilizing a hash map in the first place.
Because all values were thrown into one bucket, we have a bad hash map (that is, they are all in the same LinkedList). If this defeats hash maps, explain why.
The values have been put into a single pool, and a hash map that was not constructed with much care has resulted (that is, they are all in the same LinkedList). Give a justification for why this is counterproductive to using a hash map.
Due to the fact that all of the data were pushed into one bucket, the hash map that we constructed was not formed very correctly (that is, they are all in the same LinkedList). If this is the case, then please explain why this would defeat the objective of using the use of a hash map in the first place.
We have a hash map that was not constructed correctly, with all of the values being placed into the same bucket (that is, they are all in the same LinkedList). Explain why this is a violation of the hash map's original intent and why it should be avoided.
In this case, we have a hash map that was not constructed with a lot of care since all of the values have been lumped together (that is, they are all in the same LinkedList). In your own words, please elaborate on why this undermines the use of a hash map.
