Input : 52 peak 91 snow freeze 46 cold 15 high 31 73 trek
Step I : 15 52 peak snow freeze 46 cold high 31 73 trek 91
Step II: 15 31 52 peak snow freeze 46 cold high trek 73 91
Step III: 15 31 46 peak snow freeze cold high trek 52 73 91
Step IV: 15 31 46 cold peak snow freeze high trek 52 73 91
Step V : 15 31 46 cold peak freeze peak snow high trek 52 73 91
Step VI : 15 31 46 cold freeze high peak snow trek 52 73 91
Step VI is the last step of the rearrangement. As per the rules followed in the above steps, find out in each of the following questions the appropriate steps for the given input.
