A computer rearranges a particular input using some operations 01, 02, 03, and 04.
Input : I have long waited for your arrival.
Step 01: arrival long have waited for your I
Step 02: long arrival waited have for I your
Step 03: Your waited arrival have for I long
Step 04: Waited your have arrival for long I
If step 4 gives “I know you will not come back” what step will have “you back I come not will know”?
Solution:
Since words remain unchanged here, so this is case of either rearrangement or shifting. So, let us number each word
I = 1, have = 2, long = 3, waited = 4, for = 5, your = 6, arrival = 7
Input: 1 2 3 4 5 6 7
Step 01: 7 3 2 4 5 6 1
Step 02: 3 7 4 2 5 1 6
Step 03: 6 4 7 2 5 1 3
Step 04: 4 6 2 7 5 3 1
So, the logic being following is as follows:-
Step 01 = Swap 1st & last; 2nd & 3rd
Step 02 = Swap 1st & 2nd, last two & 3rd and 4th
Step 03 = Swap 1st & last, 2nd & 3rd.
Step 04 = 1st & 2nd, last two, & 3rd and 4th.
Since after two steps operations again repeat and hence you can guess the 5th, 6th, 7th steps.
Step 04: I know you will not come back
Step 05: back you know will not come I
Step 06: You back will know not I come
Step 07: Come will back know not I you
Step 08: Will come know back not you I
Step 09: I know come back not you will
Step 10: Know I back come not will you
Step 11: You back I come not will know
Hence step 11 is the answer.

Solution (For Qns 1-4):
The machine rearranges words and numbers in the following way. Numbers are being arranged from left side with the smallest number coming first and move subsequently so that in the last step numbers are arranged in descending order. The words are arranged from right side as they appear in English alphabetical order.
