endianness

First connect to the server: nc titan.picoctf.net 61087

Then you are given a word, in this case, "ffoxf". By using CyberChef, convert the word to hex. This should give you the Big Endian representation of the word.

Big Endian: 66666f7866

To get little-endian representation you can use online sites like this or just do it by hand.

Big Endian (space delimeter): 66 66 6f 78 66

Little Endian (space delimeter): 66 78 6f 66 66

It can be seen that by splitting to each hex character and then flipping the orientation the little-endian representation is achieved. Submit the hex values of the corresponding endian with no space delimiter to get the flag.

Little Endian: 66786F6666
