Solving Input and Output

Input and Output questions typically account for 4-5 points in the Reasoning Ability and General Intelligence sections of the various Government examinations administered throughout the nation.

Input-Output Reasoning

Input-Output reasoning is the reorganisation of data, sequence, or message consisting of words, numbers, or both, according to some rule. In Input-Output reasoning questions, a sequence of words, letters, or both is considered an input.

Candidates must trace the pattern used to reorganise the various elements of the input and then determine the required final output or final step, “elements” position, in a predetermined manner. On the basis of the elements present at input and the process used to rearrange these elements, there are numerous possible question patterns.

How to Solve Input-Output Reasoning Questions – Know All Tips and Tricks

• In the following section, candidates will find a variety of solutions to questions pertaining to input/output reasoning.

• The easiest and quickest way to determine a pattern is to identify the arrangement pattern in the final step and then work backwards to determine how the processing is to be performed.

• In shifting-type input-output reasoning, the shifting can be of varying types and involve a variety of steps; therefore, all such steps are not possible; some examples are provided below to provide a better understanding of the types of exam questions asked.

• In order to solve questions involving Input-Output reasoning, candidates should search for the patterns.

• By placing the provided words in either forward or backward alphabetical order

• By arranging the given numbers in ascending or descending order, you must find the largest and smallest.

• By writing a specific set of words in reverse order, sequentially

• By rearranging word/number positions according to a predetermined pattern

Input Output Question and  Answer

1. Examine the following material carefully and answer the questions that follow.

When given an input line of words and numbers, a word and number arrangement device rearranges them according to a specific pattern in each step. The following is an example of input and reorganisation.

Input: anticipated 20 additional humorous 31 42 sea 51 rings 26 79 happy

Step I: anticipated wittiest 20 more 31 42 sea 51 rings 26 79 happy

Step II: anticipated funniest 79 51 20 additional 31 42 sea ringing 26 happy

Step III: anticipated happiest 79 51 most joyful 20 31 42 sea rings 26

Step IV: anticipated most humorous 79 51 pleasant 42 31 20 sea rings 26

Step V: anticipated funniest 79 51 more delighted rings sea 20 26

Step VI: anticipated wittiest 79 51 joyous more rings sea 26 20

And Step VI is the final input step, as the desired layout has been achieved.

Determine, for each of the following questions, the appropriate step based on the hides used in the preceding steps.

Input: blood 21 all 25 of my 57 91 equals 59 and it fortifies 24.

In step V, how many elements are between 25 and 24?

Solution:

In the provided example:

In Step I, two words were selected, organised alphabetically, and then placed in the upper left corner.

In Step II, two numbers were selected and placed in descending order adjacent to words, followed by additional numbers.

Before answering any of the questions, we will first solve the Input String, which will make answering the questions more simpler and faster.

Input: blood 21 all 25 of my 57 91 equals 59 and it fortifies 24.

Step I: all and blood 21 25 my 57 91 equals 59 fortifies 24

Step II:  entire 91 59 blood 21 25 my 57 equals 24

Step III: entire 91 59 blood equals 21 25 my 57 fortifies 24

Step IV: total 91 59 blood equals 57 25 21 my power is increased by 24

Step V:  all 91 59 blood equals 57 25 my fortifies 21 24

Step VI:all 91 59 blood equals 57 25 my fortifies 24 21

Therefore, in our example, Step VI is the final step.

There are three items between the numbers 24 and 25.

Conclusion 

Similar to the computer idea of Input-Output, this topic’s reasoning questions require an Input in the form of numbers and words, followed by an Output that follows a specific pattern.

The input and output questions for the Machine are lengthy, time-consuming, and moderately complicated. To ensure that a candidate does not make any mistakes on these questions, it is essential to devote more time to practising them.
