TCS NQT 2020 Coding Questions

All these coding questions had appeared in TCS NQT 2020 Exam which was held in the month of August 2019.

1. One programming language has the following keywords that cannot be used as identifiers:

break, case, continue, default, defer, else, for, func, goto, if, map, range, return, struct, type, var

Write a program to find if the given word is a keyword or not

Test cases

Case 1
    Input – defer
    Expected Output – defer is a keyword

Case 2
    Input – While
    Expected Output – while is not a keyword

Q2. Given a maximum of four digit to the base 17 (10 – A, 11 – B, 12 – C, 13 – D … 16 – G} as input, output its decimal value.

Test Cases
Case 1
    Input – 1A
    Expected Output – 27

Case 2
    Input – 23GF
    Expected Output – 10980

Q3. Given a maximum of 100 digit numbers as input, find the difference between the sum of odd and even position digits

Test Cases
Case 1
Input: 4567
Expected Output: 2

Explanation : Odd positions are 4 and 6 as they are pos: 1 and pos: 3, both have sum 10. Similarly, 5 and 7 are at even positions pos: 2 and pos: 4 with sum 12. Thus, difference is 12 – 10 = 2

Case 2
    Input: 5476
    Expected Output: 2

Case 3
    Input: 9834698765123
    Expected Output: 1

Q4. Our hoary culture had several great persons since time immemorial and king vikramaditya’s nava ratnas (nine gems) belongs to this ilk. They are named in the following shloka:

Among these, Varahamihira was an astrologer of eminence and his book Brihat Jataak is recokened as the ultimate authority in astrology.

He was once talking with Amarasimha,another gem among the nava ratnas and the author of Sanskrit thesaurus, Amarakosha.

Amarasimha wanted to know the final position of a person, who starts from the origin 0 0 and travels per following scheme.

Scheme

He first turns and travels 10 units of distance
His second turn is upward for 20 units
Third turn is to the left for 30 units
Fourth turn is the downward for 40 units
Fifth turn is to the right(again) for 50 units

… And thus he travels, every time increasing the travel distance by 10 units.

Test Cases

Case 1

Input : 3

Expected Output :-20 20

Case 2

Input: 4

Expected Output: -20 -20

Case 3

Input : 5

Expected Output : 30 -20

Case 4

Input : 7

Expected Output : 90 -20

TCS NQT Previous Years Coding Questions

Q1. Consider the below series:
1, 2, 1, 3, 2, 5, 3, 7, 5, 11, 8, 13, 13, 17, ...
This series is a mixture of 2 series –all the odd terms in this series form a Fibonacci series and all th even terms are the prime numbers in ascending order. Write a program tofind the Nth term in th series.

The value N is a Positive integer that should be read from STDIN. The Nth term that is calculated by the program should be written to STDOUT. Other than the value of Nth term, no other characters/strings or message should be written to STDOUT. For example, when N = 14, the 14th term in the series is 17. So
only the value 17 should be printed to STDOUT.

Q2. Given a series whose even term creates a separate geometric series and odd term creates another geometric series. Write a program to generate such series.
For example, 1, 1, 2, 2, 4, 4, 8, 8, 16, 16,......

Q3. Find the 15th term of the series?
0,0,7,6,14,12,21,18, 28
Explanation : In this series the odd term is increment of 7 {0, 7, 14, 21, 28, 35 – – – – – – }
And even term is a increment of 6 {0, 6, 12, 18, 24, 30 – – – – – – }

Q4. Consider the following series:
1, 1, 2, 3, 4, 9, 8, 27, 16, 81, 32, 243, 64, 729, 128, 2187 …
This series is a mixture of 2 series – all the odd terms in this series form a geometric series and all the even terms form yet
another geometric series. Write a program to find the Nth term in the series.
The value N in a positive integer that should be read from STDIN. The Nth term that is calculated by the program should be written to STDOUT.

Other than value of n th term,no other character / string or message should be written to STDOUT. For example , if N=16, the 16th term in the series is 2187, so only value 2187 should be printed to STDOUT.
You can assume that N will not exceed 30.

Q5. Consider the below series :
0, 0, 2, 1, 4, 2, 6, 3, 8, 4, 10, 5, 12, 6, 14, 7, 16, 8
This series is a mixture of 2 series all the odd terms in this series form even numbers in ascending order and every even terms is derived from the previous term using the formula (x/2)
Write a program to find the nth term in this series.
The value n in a positive integer that should be read from STDIN the nth term that is calculated by the program should be written to
STDOUT. Other than the value of the nth term no other characters /strings or message should be written to STDOUT.
For example if n=10,the 10 th term in the series is to be derived from the 9th term in the series. The 9th term is 8 so the 10th
term is (8/2)=4. Only the value 4 should be printed to STDOUT.
You can assume that the n will not exceed 20,00
