A word arrangement machine takes an input line of words and rearranges them according to a specific rule in each step. The following example illustrates the process:

Input: mgtuh kaops abewm bwxef mctqe aokpw

Step I: oivuj maoru adeyo dyzeh oevse aomry
Step II: adeyo aomry dyzeh maoru oevse oivuj
Step III: adeoy amory dehyz amoru eeosv ijouv
Step IV: 26 26 30 22 27 31
Step V: 3 4 4 8 8 9

Step V is the final step for the given input.

Based on the same process, consider the input:

helof kpest fumap hseub lmodu karlx

What is the difference between the number which is second from the right end in Step IV and the number which is third from the left end in Step V?
