TCS conducts NQT in every 3months ,so in every 3months we comes with the sollution for every questions and here it is. In before tcs conducts this test in free of cost but now tcs charge for the NQT test and also offers palcements in other companies. if you score more than 1300 in NQT then you get a call for tcs interview else if you secure 1000 or less 1200 then you got a call from other companies. that’s all

TCS NQT Coding Question 2021 – Day 1 – Slot 1

QUESTION 1:

There is a JAR full of candies for sale at a mall counter. JAR has the capacity N, that is JAR can contain maximum N candies when JAR is full. At any point of time. JAR can have M number of Candies where M<=N. Candies are served to the customers. JAR is never remain empty as when last k candies are left. JAR if refilled with new candies in such a way that JAR get full.
Write a code to implement above scenario. Display JAR at counter with available number of candies. Input should be the number of candies one customer can order at point of time. Update the JAR after each purchase and display JAR at Counter.

Output should give number of Candies sold and updated number of Candies in JAR.

If Input is more than candies in JAR, return: “INVALID INPUT”

Given,

N=10, where N is NUMBER OF CANDIES AVAILABLE

K =< 5, where k is number of minimum candies that must be inside JAR ever.

Example 1:(N = 10, k =< 5)

Input Value
- 3
Output Value
- NUMBER OF CANDIES SOLD : 3
- NUMBER OF CANDIES AVAILABLE : 7

Example : (N=10, k<=5)

Input Value
- 0
Output Value
- INVALID INPUT
- NUMBER OF CANDIES LEFT : 10

#include
int main()
{
int n=10, k=5;
int num;
scanf(“%d”,&num);
if(num>=1 && num<=5)
{
printf("NUMBER OF CANDIES SOLD : %dn",num);
printf("NUMBER OF CANDIES LEFT : %d",n-num);
}
else
{
printf("INVALID INPUTn");
printf("NUMBER OF CANDIES LEFT : %d",n);
}
return 0;
}

#include <iostream.h>
using namespace std;
int main()
{
	int n=10, k=5;
	int num;
	cin>>num;
	if(num>=1 && num<=5)
	{
    	cout<< "NUMBER OF CANDIES SOLD : "<<num<<"n";
    	cout<<"NUMBER OF CANDIES LEFT : "<<n-num;
	}
	else
	{
    	cout<<"INVALID INPUTn";
    	cout<<"NUMBER OF CANDIES LEFT : "<<n;
	}
	return 0;
}

import java.util.Scanner;
class Main{
    public static void main(String[] args) {
   	 int n = 10, k = 5;
   	 int num;
   	 Scanner sc = new Scanner(System.in);
   	 num = sc.nextInt();
   	 if(num >= 1 && num <= 5) {
   		 System.out.println("NUMBER OF CANDIES SOLD : " + num);
   		 System.out.print("NUMBER OF CANDIES LEFT : " + (n - num));
   	 } else {
   		 System.out.println("INVALID INPUT");
   		 System.out.print("NUMBER OF CANDIES LEFT : " + n);
   	 }
    }
}

total_candies = 10
no_of_candies = int(input())
if no_of_candies in range(1, 6):
	print('No. of Candies Sold:',no_of_candies)
	print('No. of Candies Left:',total_candies-no_of_candies)
else:
	print("Invalid Input")
	print('No. of Candies Left:',total_candies)

QUESTION NO 2:

Selection of MPCS exams include a fitness test which is conducted on ground. There will be a batch of 3 trainees, appearing for running test in track for 3 rounds. You need to record their oxygen level after every round. After trainee are finished with all rounds, calculate for each trainee his average oxygen level over the 3 rounds and select one with highest oxygen level as the most fit trainee. If more than one trainee attains the same highest average level, they all need to be selected.

Display the most fit trainee (or trainees) and the highest average oxygen level.

Note:

The oxygen value entered should not be accepted if it is not in the range between 1 and 100.
If the calculated maximum average oxygen value of trainees is below 70 then declare the trainees as unfit with meaningful message as “All trainees are unfit.
Average Oxygen Values should be rounded.

Example 1:

INPUT VALUES

OUTPUT VALUES
- Trainee Number : 1
- Trainee Number : 3

Note:

Input should be 9 integer values representing oxygen levels entered in order as

Round 1

Oxygen value of trainee 1
Oxygen value of trainee 2
Oxygen value of trainee 3

Round 2

Oxygen value of trainee 1
Oxygen value of trainee 2
Oxygen value of trainee 3

Round 3

Oxygen value of trainee 1
Oxygen value of trainee 2
Oxygen value of trainee 3
