' Challenge 119
'
' TASK #1 - Swap Nibbles
' Submitted by: Mohammad S Anwar
' You are given a positive integer $N.
'
' Write a script to swap the two nibbles of the binary representation of the
' given number and print the decimal number of the new binary representation.
'
' A nibble is a four-bit aggregation, or half an octet.
'
' To keep the task simple, we only allow integer less than or equal to 255.
'
' Example
' Input: $N = 101
' Output: 86
'
' Binary representation of decimal 101 is 1100101 or as 2 nibbles (0110)(0101).
' The swapped nibbles would be (0101)(0110) same as decimal 86.
'
' Input: $N = 18
' Output: 33
'
' Binary representation of decimal 18 is 10010 or as 2 nibbles (0001)(0010).
' The swapped nibbles would be (0010)(0001) same as decimal 33.
dim n as integer
n = val(command(1))
n = ((int(n / 16) mod 16) + ((n mod 16) * 16))
print n
