Answer: Following code is in python
n=input()
num='1'
while int(num)<=int(n): //loop from 1 to n
flag=1 //if an unequal element will be found it will be 0
l=len(num)
if num[0]=='3':
j=0
k=l-1
while j<k: //loop till middle of number
if num[j]==num[k]:
j+=1 //from beginning
k-=1 //from end
else:
flag=0
break
if flag==1:
print(int(num))
num=str(int(num)+1) //number will be incremented as integer
INPUT :
1000
OUTPUT :
3
33
303
313
323
333
343
353
363
373
383
393
Explanation:
In the above code, a loop is executed till num is equal to n which is entered by the user. num is treated as a string so that to ease the process of checking first character is 3 or not. If it is 3 then another loop executes which checks if an element from starting is equal to the corresponding element from the end. If an element is not equal then the flag is changed and then we break out of the loop and prints the number if the flag isn't changed.
DES is a commonly used symmetric encryption
A) is a commonly used symmetric encryption
<u>Explanation:</u>
DES stands for Data Encryption Standard. It is a symmetric key algorithm and is used for encrypting electronic data. It was developed in 1975. DES is one of the oldest encryption standards to be used in the industry.
The algorithm takes 16 rounds of permutations in order to encrypt data. But now, with the advent of technology, as new algorithms have been designed and put in use, DES is less preferable.
In the process of key generation, some keys generated sometimes turn out to be weak and hence are prone to attacks. If not for the weak keys generation, DES works perfectly fine and is an effective algorithm to encrypt data.
