TCS ninja online test instructions! Dear all, some of the key points to note for the candidates : 1.Candidates need to carry 2 copies of hall ticket, college ID card and any govt ID proof 2.If any of the candidate do not have their original ID proof they can bring a copy of it, that would be suffice. 3.Scientific calculator and other electronic gadgets are not allowed inside the examination hall. With respect to test : 1.Candidate in the coding section need to scroll down the page and check the output message post compiling. 2.Process to use debugger : When students use debugger they will have to select File> new > project selection (Java c++) > give the project name > click the file>Next> Save or Finish Left side the project name would have been created : Select that file > File> File > Give a project name and save it > Type the code> Run 3.1/3rd of negative marking for all MCQs 4.After every answer the candidate has to click on the submit button on screen. @Programmingg_world

Program to calculate the determinant of 2×2 matrix.

#include<stdio.h>
#include<conio.h>

void main()
{
    int a[2][2], i, j;
    long determinant;
    clrscr();

    printf("Enter the 4 elements of matrix  :\n");
    for (i = 0; i < 2; i++)
    {
        for (j = 0; j < 2; j++)
        {
            scanf("%d", &a[i][j]);
        }
    }

    printf("\nThe matrix is : \n");
    for (i = 0; i < 2; i++)
    {
        printf("\n");
        for (j = 0; j < 2; j++)
        {
            printf("%d\t", a[i][j]);
        }
    }

    determinant = a[0][0] * a[1][1] - a[1][0] * a[0][1];

    printf("\nDeterminant of 2X2 matrix: %ld", determinant);

    getch();

Solution for [Day1]

Class Day1code{
public int createPin (int input1,int input2,int input3){
int res=0,max=0;
  for(int i=0,ca=1;i<3;i++)
  {
   int a=input1%10,b=input2%10,c=input3%10;
   if(a>max)
    max=a;
   if(b>max)
    max=b;
   if(c>max)
    max=c;
   //System.out.println(a+"="+b+"="+c+"=="+res);
   if(a<b && a<c)
    res=a*ca+res;
   else if(b<c && b<a)
    res=b*ca+res;
   else
    res=c*ca+res;
   //System.out.println(a+"="+b+"="+c+"=="+res);
   input1/=10;
   input2/=10;
   input3/=10;
   ca*=10;
  }
  return (max*1000+res);

[Day 1] Create PIN using three given input numbers "Secure Assets Private Ltd", a small company that deals with lockers has recently started manufacturing digital locks which can be locked and unlocked using PINS (passwords). You have been asked to work on the module that is expected to generate PIN using three input numbers Assumptions: The three given input numbers will always consist of three digits each i.e. each of them will be in the range 100 and <999 100input 999 100 <= input2 <= 999 100 input3 < 999 Below are the rules for generating the PIN - The PIN should be made up of 4 digits - The unit (ones) position of the PIN should be the least of the units position of the three input numbers - The tens position of the PIN should be the least of the tens position of the three input numbers The hundreds position of the PIN should be the least of the hundreds position of the three input numbers - The thousands position of the PIN should be the maximum of all the digits in the three input numbers Example 1 input1 123 input2 582 input3 175 then, PIN 8122 Example 2 input1 190 input2 267 input3 853 then, PIN 9150
