Concept of Sequential Output Tracing:
Input may contain sequence of numbers or sequence of words or combination of both numbers and words. After input, a certain number of steps will be given in order to get an output. In each and every step, it will follow one rule to get next step.
Concept 1:
Problems Based on Numbers
Eg: Directions: Study the following arrangement carefully and then answer the following questions
An electronic device rearranges numbers step-by-step in a particular order according to a set of rules. The device stops when the final result is obtained. In this case the device stops at Step V.
Input : 85 16 36 04 19 97 63 09
Step I : 97 85 16 36 04 19 63 09
Step II : 97 85 63 16 36 04 19 09
Step III : 97 85 63 36 16 04 19 09
Step IV : 97 85 63 36 19 16 04 09
Step V : 97 85 63 36 19 16 09 04
1) Which of the following will be step III for the input below?
Input : 09 25 16 30 32 18 17 06
(a) 32 30 25 09 16 18 17 06
(b) 32 30 09 25 16 18 17 06
(c) 32 09 25 16 30 18 17 06
(d) 32 30 09 25 16 19 17 06
Concept 2:
Problems Based on Words
Eg: Directions: Study the following information carefully to answer these questions:
A word arrangement machine, when given an input line of words, rearranges it in every step following a certain rule. Following is an illustration of an input line of words and various steps of rearrangement.
Input : gone are take enough brought station
Step I : take gone are enough brought station
Step II : take are gone enough brought station
Step III : take are station gone enough brought
Step IV : take are station brought gone enough
And, Step IV is the last step for this input. Now, find out an appropriate step in each of the following questions following the above rule.
1) Input : car on star quick demand fat
What will be the third step for this input?
(a) star quick car demand on fat (b) star car quick demand on fat
(c) star car demand quick on fat (d) star car quick on demand fat
(e) None of these
2) Input : ink hurry yet for the victory
Which of the following will be the last step of the above input?
(a) III (b) IV (c) V (d) VI (e) None of these
Concept 3:
Problems based on both numbers & words
Eg: Directions : Study the following information carefully to answer these questions:
A word and number arrangement machine, when given an input line of words and numbers rearranges them following a particular rule in each step. The following is an illustration of an input and rearrangement.
Input : quick fire 15 28 39 war 19 yellow
Step I : yellow quick fire 15 28 39 war 19
Step II : yellow 15 quick fire 28 39 war 19
Step III : yellow 15 war quick fire 28 39 19
Step IV : yellow 15 war 19 quick fire 28 39
Step V : yellow 15 war 19 quick 28 fire 39
And Step V is the last step of the above input.
As per the rules followed in the above steps, find out in each of the following questions the appropriate step for the given input.
1) Step II of an input is : win 12 92 for 81 always 36 home
Which of the following will be Step VII?
(a) win 12 home 36 92 for 81 always
(b) win 12 home 36 for 92 always 81
(c) win 12 home 92 for 81 always 36
(d) There will be no Step VII
(e) None of these
2) Input : age die 72 53 35 hold goal 26
How many steps will be required to complete the rearrangement?
(a) Four (b) Five (c) Six (d) Seven (e) None of these
Concept 4:
Problems based on Passcodes or Passwords
Eg: Directions : Study the following information carefully to answer these questions:
The admission ticket for an exhibition bears a password which is changed after every clock hour based on set of words chosen for each day. The following is an illustration of the code and steps of rearrangement for subsequent clock hours. The time is 9 a.m. to 3 p.m.
Batch I (9 a.m. to 10 a.m.) : is not ready cloth simple harmony burning
Batch II (10 a.m. to 11 a.m.) : ready not is cloth burning harmony simple
Batch III (11 a.m. to 12 noon) : cloth is not ready simple harmony burning
Batch IV (12 noon to 1 p.m.) : not is cloth ready burning harmony simple
Batch V (1 p.m. to 2 p.m.) : ready cloth is not simple harmony burning
and so on.
1) Day’s first password – ”camel road no toy say me not”. What will be the password for fourth batch, i.e., 12 noon to 1 p.m.?
(a) road camel toy no not me say
(b) no road camel toy not me say
(c) toy no road camel not me say
(d) toy camel road no say me not
(e) None of these
2) If the password for Batch I was - ‘rate go long top we let have’, which batch will have the password - ’go rate top long have let we’?
(a) II (b) III (c) IV (d) V (e) None of these
Directions (1 – 5): Study the following information carefully to answer these questions:
A machine rearranges numbers step by step in a particular order according to a set of rules. The machine stops when the final result is obtained. In this case the machine stops at step V.
Input : 78 20 32 08 25 92 69 12
Step I : 92 78 20 32 08 25 69 12
Step II : 92 78 69 20 32 08 25 12
Step III : 92 78 69 32 20 08 25 12
Step IV : 92 78 69 32 25 20 08 12
Step V : 92 78 69 32 25 20 12 08
Study the above arrangement carefully and then answer the following questions:
Q1. Which of the following will be step IV for the input below?
Input : 12 36 20 40 52 19 18 07
A) 52 40 36 20 19 12 18 07
B) 52 36 40 20 19 12 18 07
C) 52 40 36 20 12 19 18 07
D) 52 40 20 36 19 12 18 07
SOLUTION:
Carefully observing the sample sequence, we observe that in the given arrangement, the numbers have been arranged in descending order (from left to right) in a sequence, altering the position of only one number in each step,
followed by the other numbers as it is. The process continues till the whole set of numbers is arranged in descending order.
Input : 12 36 20 40 52 19 18 07
Step I : 52 12 36 20 40 19 18 07
Step II : 52 40 12 36 20 19 18 07
Step III : 52 40 36 12 20 19 18 07
Step IV : 52 40 36 20 12 19 18 07
