Question

Input Format The first line contains a single integer N denoting the size of array. The second line contains N space-separated integers denoting the elements of the array. Constraints 1 <= N <= 100 0 <= A[i] <= 100 Output Format Print all the leaders. Sample Input 0 6 16 17 4 3 5 2 Sample Output 0 17 5 2 Sample Input 1 5 5 4 3 2 1 Sample Output 1 5 4 3 2 1

Answer 1

Explanation:

the array has size to only hence possible split can be only three or four hands the answer is 4- 3=1

Answer 2

The first line contains a single integer N denoting the size of the array. The second line contains N space-separated integers denoting the elements of the array. Constraints 1 <= N <= 100 0 <= A[i] <= 100

SOURCE CODE:

#include <stdio.h>

#include <stdlib.h>

int main()

{

   int num, *arr,*arr2,i;

   scanf("%d", &num);

   arr = (int*) malloc(num * sizeof(int));

   for(i = 0; i < num; i++) {

       scanf("%d", arr + i);

   }

   arr2 = (int*) malloc(num * sizeof(int));

   for(i=1;i<=num;i++)

   {

       arr2[i-1] = arr[num-i];

   }

   for(i = 0; i < num; i++)

       printf("%d ", *(arr2 + i));

   return 0;

}

Explanation:

• In the main function, the variable and pointers are initialised (num, *arr1, *arr2).
• After which, the malloc function is used with pointers arr1 and arr2.
• To dynamically allocate a single huge block of memory with the required size in C, use the "malloc" or "memory allocation" method. It gives back a void pointer that can be cast into any other kind of pointer.
• Using the function, it will start from the initial value till the value entered and give the appropriate output.
• After the execution, it will print the output with the help of a pre-defined print function.
