WebA Simple Proof. My simple proof shows that binary function, 3n + b, where n is the number and b is the least significant bit (LSB), is the same as the Collatz function. This is my proof. The LSB/rightmost bit of a number determines if it is even or odd (true) Every odd number 2x+1 becomes 3 (2x+1)+1 = 6x+4 by Collatz rules then (6x+4)/2 = 3x+2 ... WebThis post lists the learnings from the CTF while doing Reverse Engineering.
