In the first step, the largest number comes to the first position and the remaining line shift rightward. In the next step the word that comes first in the alphabetical order goes on to occupy the second position pushing the rest of the shift rightward. This goes alternately till all the number are arranged in a descending order and all the words in alphabetical at alternate positions.

Input : 14 35 when they came 61 48 home
Step I : 61 14 35 when they came 48 home

In the first step, the word that comes first in the alphabetical order comes to the first and the rest of the shift rightward. In the next step largest number occupies the next place and the rest of the shift rightward. This goes on alternately till the words get arranged in the reverse alphabetical order and number in a descending order.

Step III: years 92 ultra 15 23 strive house 39
Step IV: years 92 ultra 39 15 23 strive house
Step V: years 92 ultra 39 strive 15 23 house
Step VI: years 92 ultra 39 strive 23 15 house
Step VII: years 92 ultra 39 strive 23 house 15
Hence 7 ? 3 = 4 more steps will be required.

In the first step, the word that comes first in the alphabetical order comes to the first and the rest of the shift rightward. In the next step largest number occupies the next place and the rest of the shift rightward. This goes on alternately till the words get arranged in the reverse alphabetical order and number in a descending order.
