Answer:
You need exit condition like If, otherwise method will repeat endlessly.
Answer:
Binary sort
Explanation:
Binary sort is one of the fastest search techniques used on arrays and other iterable data types. It algorithm sorts the array in ascending order then gets the item in the middle from which it divides the array to be searched in two parts. If the searched term is less than the mid item, then it is searched for in the first part, else it would be in the second.
Answer:
The program to this question as follows:
Program:
def lettersOnly(s): #defining method lettersOnly
val="" #defining string variable that return value
for i in s: #defining loop to calculate value
if(i.isalpha()): #check condition that value is string
val=val+ i #add value
return val #return value
print(lettersOnly("data3base_ro1c3k5s")) #call method and print value
Output:
databaserocks
Explanation:
In the above python code, a method lettersOnly is declared that accepts a string variable "s" in its parameter. Inside the method, a string variable "val", and loop is declared, in which the "val" variable holds method return value.
- In the loop and if block is used that uses "isalpha" string method, which checks the check alphabetic character in the given value. if this is true it will calculate all value in "val" variable and return its value.
- At the last, the print method is used, which calls the lettersOnly method and prints its return value.
Answer:
The first HDD was created by IBM in 1956 and was the size of a refrigerator. The total storage capacity was 5 MB and only two heads were used to read the disks. The 1970s offered a hard disk drive in much smaller shells with the ability to store roughly 60 MB.
