Step-by-Step Solution
There are four numbers (6, 15, 28, 41). One number is arranged per step, so four steps are needed.
Answer: D) Four
A word-and-number rearranging machine, given an input line, produces output in steps. In each step it shifts the smallest of the not-yet-arranged numbers to the left end; numbers already shifted stay at the left in ascending order and the order of the remaining items is unchanged. Example — Input: pen 52 ink 19 map 33 cup 7; Step I: 7 pen 52 ink 19 map 33 cup; Step II: 7 19 pen 52 ink map 33 cup; Step III: 7 19 33 pen 52 ink map cup; Step IV: 7 19 33 52 pen ink map cup (final). For the input 'lamp 41 tree 15 rock 28 bird 6', how many steps are required to complete the arrangement?
