Question

Use C Programming -

Given an array of integers and a number K, find the smallest element in array greater than or equal to K. If such element exists in the array, display it otherwise display "-1".

Example:

Input:

    8

    1 3 4 7 8 9 9 10

    5

    where:

• First line represents the number of elements in the array.

Answer 1

#include <stdio.h>

int main(void) {
   int n, i,k,res=-1;
   int arr[200];
   scanf("%d",&n);
   for(i = 0;i<n;i++){
       scanf("%d",&arr[i]);
   }
   scanf("%d",&k);
   
   for(i = 0;i<n;i++){
       if(arr[i]>k){
           if(res==-1){
               res = arr[i];
           }
           else if(res-k > arr[i]-k){
               res = arr[i];
           }
       }
   }
   
   printf("%d\n",res);
    return 0;
}
