Answer:
it is something that you have to call your nearest xfinity store
i had the same problem but got it fixed
Explanation:
In conclusion there are many different data structures. Each data structure has strengths and weaknesses which affect performance depending on the task. Today, we explored two data structures: arrays and linked lists. Arrays allow random access and require less memory per element (do not need space for pointers) while lacking efficiency for insertion/deletion operations and memory allocation. On the contrary, linked lists are dynamic and have faster insertion/deletion time complexities. However, linked list have a slower search time and pointers require additional memory per element in the list. Figure 10 below summarizes the strength and weakness of arrays and linked lists.
The allocation methods define how the files are stored in the disk blocks.
There are three main disk space or file allocation methods:
1.Contiguous Allocation-in this scheme,each file occupies a set of blocks on the disk. For example if a file requires x blocks and is given a block y as the starting location,then the blocks assigned to the file be :x,y+1,y+2,......y+x-1.
This means that given the starting block address and the length of the file(in terms of blocks required) we can determine the blocks occupied by the file.
Advantages
-both the sequential and direct accesses are supported
-this is extremely fast since the number of seeks are minimal because of contiguous allocation of file blocks.
2.linked allocation-in this scheme,each file linked list of disk blocks which need not be contiguous disk blocks can be scattered anywhere on the disk.
Advantages
it is very flexible in terms of file size.file size can be increased easily since the system does not have to look for a contiguous chunk
of memory.
this method does not suffer from external fragmentation and it makes it relatively better in terms of memory utilization.
3.Indexed Allocation-in this scheme,a special block known as the index block contains the pointers to all the blocks occupied by a file.Each file has its own index block.the entry in the index block contains the disk address of the block
Advantages
it supports direct access to the blocks occupied by the file and therefore provides fast access to the file blocks
it overcomes the problem of external fragmentation.
Answer:
Not exact, but it will help.
Explanation:
do something like this.
print("""
this program will help you plan your garden.
First, we need some information about the dimensions you want.
""")
while True:
try:
response = int(input("Please enter the side length for your garden (in feet) : "))
except ValueError:
print("(!)Please Enter A Number(!)")
print("")
continue
if str(response) == "":
continue
else
length = int(response)
break
repeat stuff like that up above for the rest, and then you can decide what to do with the variables and how they need to be multiplied for the output. Good luck!
