Problem description

Hexadecimal number is a kind of integer expression that is often used in program design . It has 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F common 16 Symbols , They represent decimal numbers respectively 0 to 15. The hexadecimal counting method is full 16 Into the 1, So decimal numbers 16 In hexadecimal it's 10, And decimal 17 In hexadecimal it's 11, And so on , Decimal 30 In hexadecimal it's 1E.
Give a nonnegative integer , Express it in hexadecimal form .

Input format

The input contains a non negative integer a, Represents the number to convert .0<=a<=2147483647

Output format

The output of this integer is 16 Hexadecimal said

The sample input

30

Sample output

1E

Implementation code

n=input()
k=hex(int(n))
print(k[2:].upper())

matters needing attention

use hex（） The hexadecimal number output by the function after conversion is represented by lowercase letters by default
In this case upper（） Function to convert upper and lower case letters

m = 'qeddQSD'
m.upper()# All capitals 
m.lower()# All letters lowercase 
m.capitalize()# title case , Other letters are lowercase 
m.title()# Capitalize the first letter of each word , Other lowercase 

At the same time, the first two decimal symbols of the number shall be omitted during output

k = 'ox1e'
print(k[2:])
