# ch-5 :- Input-Output : Exercise 2

⇒ Directions for Q. No. 1 to 5 : A word arrangement machine, when given an input line of words, rearranges them following a particular rule in each step. The following is an illustration of input and steps of rearrangement.

Input    : ‘the most typical is set for action.’

Step I    : typical most the set is action for.

Step II    : most typical is set the for action.

Step III    : typical most set is action for the.

Step N    :  set most typical action is the for

(and so on) ……..

Study the pattern and then answer the following questions

1. Input: ‘why do you worry for your study.’ ‘ Which of the following will be the yth step?

(a) do for why you ……

(c) do for worry study……

(d) do for study worry ……

(e) None of the above

Ans(c)

From above illustration, it is clear that in step I word marked with 1 is interchanged with 3, 4 with 5, and 6 with 7, keeping the word marked 2 as it is. In step II, word marked 5 is kept same and 2 is interchanged with 3,4 with 1, and 6 with 7. Likewise in third step, word marked with 6 is kept same and 2 is interchanged with 3,5 with 4 and, 1 with 7. Now, step IV is again identical to step I and so on

yth step for the given input will be 2 5 4 7 361, which is obtained after continuing the step IV given in the illustration. Hence, the yth step is, do for worry study…….

2. ‘set for the table is their black’, is the fourth step of a given input. Which of the following will be the input?

(a) their for the is set table black.

(b) their for the set is table black.

(c) their for the is set black table.

(d) None of the above

Ans(c)

From above illustration, it is clear that in step I word marked with 1 is interchanged with 3, 4 with 5, and 6 with 7, keeping the word marked 2 as it is. In step II, word marked 5 is kept same and 2 is interchanged with 3,4 with 1, and 6 with 7. Likewise in third step, word marked with 6 is kept same and 2 is interchanged with 3,5 with 4 and, 1 with 7. Now, step IV is again identical to step I and so on

IVth step is of the order: 5 2 3 7 4 1 6, i.e. ‘set for the table is their black’. Hence, input for this step will be : 1 234567 i.e., ‘their for the is set black table’

3. Which word will come in the fourth place in the second step of the input : ‘Success comes in disguise as hard-work’?

(a) as     (b) comes    (c) disguise

(d) success     (e) None of these

Ans(a)

From above illustration, it is clear that in step I word marked with 1 is interchanged with 3, 4 with 5, and 6 with 7, keeping the word marked 2 as it is. In step II, word marked 5 is kept same and 2 is interchanged with 3,4 with 1, and 6 with 7. Likewise in third step, word marked with 6 is kept same and 2 is interchanged with 3,5 with 4 and, 1 with 7. Now, step IV is again identical to step I and so on

IInd step of the input is of the order: 2 3 4 5 1 6 7. Therefore, fifth word of the input is at the fourth place of IInd step. Hence, word ‘as’ will be at the fourth place.

4. If the ‘our call to all those who dream’, be the first step of a given input, then which of the following will be the third step?

(a) call our all to dream those who.

(b) our call to all who those dream.

(c) our call all those who dream to.

(d) our call those all dream who to.

(e) None of the above

Ans(c)

From above illustration, it is clear that in step I word marked with 1 is interchanged with 3, 4 with 5, and 6 with 7, keeping the word marked 2 as it is. In step II, word marked 5 is kept same and 2 is interchanged with 3,4 with 1, and 6 with 7. Likewise in third step, word marked with 6 is kept same and 2 is interchanged with 3,5 with 4 and, 1 with 7. Now, step IV is again identical to step I and so on

5. Which of the following will be the vth step of the input as given in the illustration?

(a) most set is action typical ……

(b) most set action is typical …….

(c) set most is action typical …….

(d) most set action is typical …….

(e) None of the above

Ans(a)

From above illustration, it is clear that in step I word marked with 1 is interchanged with 3, 4 with 5, and 6 with 7, keeping the word marked 2 as it is. In step II, word marked 5 is kept same and 2 is interchanged with 3,4 with 1, and 6 with 7. Likewise in third step, word marked with 6 is kept same and 2 is interchanged with 3,5 with 4 and, 1 with 7. Now, step IV is again identical to step I and so on

vth step of any given input is of the order: 2 5 4 7 3 6 l. Therefore, the vth step for the input given in the illustration will be ‘most set is action typical…………

⇒ directiens for Q. No. 6 to 9 : Study the following information to answer the given questions. A word arrangement machine, when given an input line of words, rearranges them following a particular rule in each step. The following is an illustration of input and the steps of rearrangement.

Input   : ‘As if it on as zoo figure Of in at’

Step I   : as As if it on zoo figure Of in at

Step II   : as As at if it on zoo figure Of in

Step III   : as As at figure if it on zoo Of in

Step IV   : as As at figure if in it on zoo Of.

Step V   : as As at figure if in it Of on zoo

(and step V is the last step for this input)

As per the rules followed in the above steps, find out in the questions below, the appropriate steps for the given inputs:

6. Input: ‘you are at fault on this’-Which of the following steps would be ‘are at fault on you this’ ?

(a) I     (b) II     (c) III     (d) IV    (e) V

Ans(d) Here each word of the input has been arranged in the alphabetical order giving preference to the word starting with the small letter.

Input  : you are at fault on this’

Step I  : are you at fault on this.

Step II  : are at you fault on this.

Step III  : are at fault you on this.

Step IV  : are at fault on you this

7. Input: ‘am ace all if Is’-Which of the following will be the IInd step?
