def toCamelCase(str):
string = str.replace("-", " ").replace("_", " ")
string = string.split()
if len(str) == 0:
return str
return string[0] + ''.join(i.capitalize() for i in string[1:])
print(toCamelCase("the-stealth-warrior"))
Explanation:
I will explain the code line by line. First line is the definition of toCamelCase() method with str as an argument. str is basically a string of characters that is to be converted to camel casing in this method.
string = str.replace("-", " ").replace("_", " ") . This statement means the underscore or dash in the entire are removed. After removing the dash and underscore in the string (str), the rest of the string is stored in string variable.
Next the string = string.split() uses split() method that splits or breaks the rest of the string in string variable to a list of all words in this variable.
if len(str) == 0 means if the length of the input string is 0 then return str as it is.
If the length of the str string is not 0 then return string[0] + ''.join(i.capitalize() for i in string[1:]) will execute. Lets take an example of a str to show the working of this statement.
Lets say we have str = "the-stealth-warrior". Now after removal of dash in by replace() method the value stored in string variable becomes the stealth warrior. Now the split() method splits this string into list of three words the, stealth, warrior.
Next return string[0] + ''.join(i.capitalize() for i in string[1:]) has string[0] which is the word. Here join() method is used to join all the items or words in the string together.
Now i variable moves through the string from index 1 and onward and keeps capitalizing the first character of the list of every word present in string variable from that index position to the end. capitalize() method is used for this purpose.
So this means first each first character of each word in the string starting from index position 1 to the end of the string is capitalized and then all the items/words in string are joined by join() method. This means the S of stealth and W of warrior are capitalized and joined as StealthWarrior and added to string[0] = the which returns theStealthWarrior in the output.
The number of bits in the physical address is 26 bits. The number of entries in a page table is entries. The size of the page table in a one-level paging scheme is 4MB.
What is paging in Operating System?</h3>
Paging is a storage method used in operating systems to recover activities as pages from secondary storage and place them in primary memory. The basic purpose of pagination is to separate each procedure into pages.
We are given the following parameters:
- 32-bit logical address
- Page size = 4 KB =
- Size of each Page table entry = 4 bytes
Suppose the system supports physical memory size = 64 MB =
Thus, the number of bits in the physical address is computed as:
=
= 26 bits
The number of entries in a page table = logical address space size/page size
The number of entries in a page table
entries
In a one-level paging scheme, the size of the table is:
= entire no. of page entries × page table size
=
= 4 MB
b.
suppose that this system supports up to 2^30 bytes of physical memory.
- The size of the page table will be the same as 4 MB due to the fact that the number of entries, as well as, the page table entry size is the same.
Since the size of the page table surpasses that of a single page. A page cannot include a whole page table. Therefore, the page table must be broken into parts to fit onto numerous pages, and an additional level of the page table is required to access this page table.
- This is called the Multi-Level Paging system.
Therefore, we can conclude that the number of bits in the physical address is 26 bits, the number of entries in a page table is entries, and the size of the page table in a one-level paging scheme is 4MB.
