Not the answer you're looking for? There is no need to use the Third loop to check the second largest number in the array. Like this: int mymaximum (int a [], int numberOfElements) { // moved code from main () to here int mymaximum = 0; for (int i = 0; i < numberOfElements; i++) { if (a [i] > mymaximum) { mymaximum = a [i]; } } return mymaximum; } Conceptually, how would you do find the largest number in an array (list, or set)?

Semantics of the `:` (colon) function in Bash when used in a pipe? please refer to Arrays in C to understand the concept of size, index position, etc. Considering the first element of the array to be the largest, compare all the remaining elements of the array, and change the largest value if assumed largest element is smaller than the element being compared. max1 = max2 = INT_MIN. a[0]. rev2023.6.2.43474. Follow the steps below to implement this idea: Below is the implementation of the above approach: Time complexity:O(N), to traverse the Array completely.Auxiliary Space: O(1), as only an extra variable is created, which will take O(1) space. Time complexity:O(N), since the in-built max_element() function takes O(N) time.Auxiliary Space: O(1), as only an extra variable is created, which will take O(1) space. Barring miracles, can anything in principle ever establish the existence of the supernatural? This program finds the largest element in an array.

They are doing it by some different approach. Though when we generalized it, no doubt it'll come to O(n^2), but specifically here shouldn't it be (constant * O(n)) ? Required fields are marked *. START Step 1 Take an array A and define its values Step 2 Declare largest as integer Step 3 Set 'largest' to 0 Step 4 Loop for each value of A Step 5 If A [n] > largest, Assign A [n] to largest Step 6 After loop finishes, Display largest as largest element of array STOP Pseudocode Let's now see the pseudocode of this algorithm There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data.
