Short Method for Input Output Problems
INPUT OUTPUT PROBLEMS
Consider the following problem
Input : Sale data 18 23 for 95 then 38
Step I : data sale 18 23 for 95 then 38
Step II : data 95 sale 18 23 for then 38
Step III : data 95 for sale 18 23 then 38
Step IV : data 95 for 38 sale 18 23 then
Step V : data 95 for 38 sale 23 18 then
Step VI : data 95 for 38 sale 23 then 18
And step VI is last step
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Now short approach to solve this is not to see whole pattern but directly see the last step. Generally it will arrange
words according to dictionary in forward or reverse manner and digits also in ascending or descending form. It could
be any pattern given by the examiner, but in almost all cases you will be able to figure out the pattern by watching the
last step only
In this question we can see in last step that ENGLISH alphabets are in dictionary order starting from
A to Z and numbers are in descending order, so our half work is done… as we know the pattern of the arrangement
i.e. first an english letter with higher order, then highest number, then english letter in ascending number, then
number just less than highest number and so on…….
One more step is to see that words are arranged in each step by shifting or swaping
Shifting : shifting means tat desire numberor alphabet comes to its place and all the words and letters are shifted as it
is after that word
For eg
data goat solo eat her zoo
now eat has to come before goat so we shift it as
data eat (goat solo her zoo) arranged as it is
Swapping : In this type one word is replaced by other one

For eg
Data goat solo eat her zoo
We swap it as
Data eat solo goat her zoo
(here eat and goat are interchanged)
Now as per the present scenario we mostly have shifting type of pattern and we have a short trick for it to
find answers of question
If it is given in question that Second step of input is so and so find fifth step, so in these question instead of solving it
completely, we can see that if given step issecond step so AT LEAST two words are already arranged so look at the
given stucture that if 2 or 3 or how many words are arranged after that instead of writing it step by step cut the words
with PENCIL which are arranged and then cut the nextword which should come next and increase the counter of the
steps i.e. step 3 in your mind, then cut next word that should come in the arrangement and increase step counter.
One thing that is to be noted that is you should not worry about the arrangement that should come after shifting
because after cutting the word in the arrangement, the uncut words will always make correct pattern after shifting.
In some cases the required word or number which is to be arranged is first letter in the first letter of the resulting
arrangement, in this case we will cut tha word or number but we will not increase the step counter as we do not have
to shift it anywhere, it was already at its place
For eg
It is given that first step of the arrangement is
Data eat solo goat her zoo
Then according to the rule at least one word is already in its place i.e. data is in its correct place, now we check
the next letter EAT, and we find that this too is on its correct place so 2 letters are already arranged
solo goat her zoo (Step I)
so we first cut these words and proceed forward to check out next letter in the arrangement, and we find
that next letter should be GOAT, so we cut it and increase the step counter so it will be our Step II.
solo her zoo (Step II)
Then next word should be HER so we cut that letter and increase the counter by one and it becomes step number III
solo zoo (Step III)
After step III we find our next letter of the arrangementwhich should be SOLO, so we will cut that letter BUT
COUNTER FOR STEP NUMBER WILL NOT INCREASE because it is already in its place. So we are still on step III.
zoo (Step III)

After this we will look out for next letter which is ZOO, so we will cut it and this time also we will not increase the step
counter as it is also on its correct place.
(Step III)
* Generally there is a question in which it is asked that step III or any step of the arrangement is so and so, then he
asks any of the previous steps than step III or whichever step is given, step I or step II in this case. In these question
the answer will be CANNOT BE DETERMINED.
Explanation : For these type of question answer will be CBD as we can see in above example also that the word
which is to be arranged can come from any where i.e. its position could be anywhere in the given pattern before
actual arrangement, we can see that goat comes before solo in the above example after actual arrangement, but in
the provided input it was after SOLO, so position of any word cannot be determined in previous step and hence we
cannot find pattern of previous step.
I think i made myself very clear with this method.
