What Is The Time Complexity Of The Following Implementation Of #1815

What is the time complexity of the following implementation of linear search on a linked list?</p> <pre><code class="language-c"> #include<stdio.h> #include<stdlib.h> struct Node { int val; struct Node* next; }*head; int linear_search(int value) { struct Node *temp = head->next; while(temp != 0) { if(temp->val == value) return 1; temp = temp->next; } return 0; } int main() { int arr[5] = {1,2,3,4,5}; int n = 5,i; head = (struct Node*)malloc(sizeof(struct Node)); head->next = 0; struct Node *temp; temp = head; for(i=0; i<n; i++) { struct Node *newNode = (struct Node*)malloc(sizeof(struct Node)); newNode->next = 0; newNode->val = arr[i]; temp->next = newNode; temp = temp->next; } int ans = linear_search(-1); if(ans == 1) printf("Found"); else printf("Not found"); return 0; }</code></pre>

This multiple choice question (MCQ) is related to the book/course gs gs122 Data Communication and Computer Network. It can also be found in gs gs122 Recursion - Search an Element in a Linked List using Recursion - Quiz No.1.
