Input OutputQuestions Input Output Questions

These types of questions regularly come in the competitive

examinations. Although they may look complex but they are

not so tough. Only factor in that they are time-consuming

and time is premium in a competitive test these days.

What is this

Generally one is asked to imagine that there is some kind of

computer or Machine. This machine have to given a

instruction to perform certain kind of action in each step

after that is gave a desire output.

Consider the following Input Output Questions 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

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

XXXX

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 is second 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 next

word 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 ornumber 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

Data eat 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.

Data eat solo goat 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

Data eat solo goat her 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.

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.


* 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.

Shortcut Guideline to solve Input Output Questions

(1) 1st see output then input because without knowing what

is final result you may be confused.

Let suppose there is a pen it made with ink, nib, plastic

cover etc. first if you will see the pen then you imagine how

this pen made. Otherwise you have to give ink, nib plastic

cover than you not imagine what happened. So, 1st step

should be see the output.

(2) 2nd step is the see input.

(3) 3rd step is see other steps that how the output formed.

Remember for Input Output Questions

(1) We cannot find previous step means if 5th step or

4th step is given and we have to find out 3rd, 2nd and input.

Then we cannot find it. So, our answer will be Cannot be

determined
