NPTEL - WEEK 4 ASSIGNMENT 4 - QUESTION 03

 WEEK 4 - ASSIGNMENT 4 - QUESTION 03

QUESTION :

Given a threshold floating point number and an array of floating point numbers strictly between 0 and 1.

    Modify the array with the following rules: If the number is greater than threshold value, change it to 1 and if less 

    than or equal to threshold value, change to 0.

    

    Output the sum of the modified array.

    Constraint: Array contains atmost 20 elements.

    Input: First line contains the threshold value.

           Next line gives the size of an array.

           Next line provides the content of an array.

          

    Output: Sum of modified array.

Example:   Input:

            0.3

            4

            0.1 0.9 0.11 0.98

           

           Modified array: 0 1 0 1

           Output : 2

SOLUTION :

#include<stdio.h>

int main()
{
    float num[20], tshld;
    int sum=0, n;

    scanf("%f", &tshld);
    scanf("%d", &n);

    for(int i=0; i<n; i++)
    {
        scanf("%f", &num[i]);
    }

    for(int i=0; i<n; i++)
    {
        if(num[i] > tshld)
        {
            num[i] = 1.0;
        }
        else if(num[i] <= tshld)
        {
            num[i] = 0.0;
        }
    }
    for(int i=0; i<n; i++)
    {
        sum += num[i];
    }
    printf("%d", sum);
    return 0;
}

WEEK 4 - ASSIGNMENT 4 - QUESTION 01

QUESTION :

Given two arrays of integers output the largest number in the
first array not present in the second one.

Input: 

The first line contains the size of the first array.
Next line give the contents of the first array.
Next line contains the size of the second array.
Next line give the contents of the second array.

Output Format:
Output must be a single number which is the largest number occurring
in the first array that does not occur in the second. In case there is
no such number, output 0.

Variable Constraints:
The sizes of the arrays are smaller than 20.
Each array entry is an integer which fits an int data type.

Example:
Input:
3
2 3 4
4
1 4 5 7

Output: 3

Input
1
1
2
1 2

Output: 0

SOLUTION :

#include<stdio.h>
int main()

{

    int arr1[10], max, count, arr2[10], n=0, m=0;
    scanf("%d", &n);

    for(int i=0; i<n; i++)

    {

        scanf("%d", &arr1[i]);

    }
    scanf("%d", &m);

    for(int j=0; j<m; j++)

    {

        scanf("%d", &arr2[j]);

    }
    while(1)

    {

        max = 0;

        count = 0;

        for(int i=0; i<n; i++)

        {

            if(max < arr1[i])

            {

                max = arr1[i];

                count = i;

            }

        }

        for(int j=0; j<m; j++)

        {

            if(max == arr2[j])

            {

               arr1[count] = 0;

               

            }

            

        }

        if(arr1[count] != 0)

        {

            break;

        }

        if(max == 0)

        {

           break;

        } 

    }

    

    printf("%d", max);
