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

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
