Given an input line of numbers and words, a machine rearranges them following particular rule in each step. Here is an illustration of an input and rearrangement sequence (Step 1 to Step 5) :
Input: 61 wb ob 48 45 29 34 sb pb lb
Step 1: lb wb ob 48 45 29 34 sb pb 61
Step 2: lb ob wb 45 29 34 sb pb 61 48
Step 3: lb ob pb wb 29 34 sb 61 48 45
Step 4: lb ob pb sb wb 29 61 48 45 34
Step 5: lb ob pb sb wb 61 48 45 34 29
Step 5 is the last step of the above arrangement.
Based on the rules followed in the above steps, answer the following question :
Input: cb kb eb 58 49 23 38 jb nb gb 69 82
Which of the following represents the position of 58 in the fourth step? (Step-5 is the last step of the arrangement.)
