Hi all, not really sure if this is in the right forum but I would like your input on this challenge of the week. It is labeled as very challenging and looks a little over my head.

"Two distinct positive integers are chosen. The square of the smaller integer is computed. The larger integer is replaced with the absolute difference of the two original integers. The process continues with the absolute value and the smaller integer. From these, the square of the smaller integer is computed and the larger integer is replaced with the absolute value of the difference. This process is continued until the difference is zero. What is the sum of the squares that have been computed? Justify your answer."

Again if it's in the wrong forum let me know but your help would be greatly appreciated.
