Input-Output 

It is basically the arrangement of a data in a particular sequence to get a determined step.
Eg. 
Input : car tiger dog umbrella owl apple 
S1: apple car tiger dog umbrella owl
S2: apple car tiger dog umbrella owl
S3: apple car dog tiger umbrella owl
Q. If Input is '   amar akbar anthony 'then find out the Step I.
  Sol: 
S1: akbar amar anthony
the above example is based on shifting problems

1. Shifting Problems

In the shifting problems any possible steps can be determined could be possible in backward or forward order which is not possible in some other problems.the shifting can be of various types so conclude all such steps would not be possible.

2. Arrangement Problems 

In such problems , To getting on a desire outcome or to find out a pre-determined step 'the sequence' of the data is matters a lot. In such cases or problems the previous step can never be determined.so we call that problems 'cannot be determined'.

Input  tom 41 19 rubber 92 88 31 wolf jam house 22 bus 72 apple
Step I : 92 tom 41 19 rubber 88 31 wolf jam house 22 72 apple bus
Step II: 92 88 tom 41 19 rubber 31 wolf jam 22 72 apple bus house
Step III: 92 88 72 tom 41 19 rubber 31 wolf 22 apple bus house jam
Step IV: 92 88 72 41 tom 19 31 wolf 22 apple bus house jam rubber
Step V: 92 88 72 41 31 19 wolf 22 apple bus house jam rubber tom
Step VI: 92 88 72 41 31 22 19  apple bus house jam rubber tom wolf
Step VI is the last step of the rearrangement.

4. Miscellaneous Problems 

All those problems which does not contains any specific order sequence or logic or patterns which could be in any way those are defined in a miscellaneous category because there is no fixed pattern of question Infact, questions under this category come before you as a real surprise.

There is no fixed pattern in regard of statement. Statement under this category will come before you as a real surprise.Such question are complete mind game.
