How do you find the largest and second largest number in an array?

The program output is also shown below.

1. * C program to read elements into an array and find the.
2. * largest two elements in a given array.
3. int n = 0, i = 0, largest1 = 0, largest2 = 0, temp = 0;
4. printf (“Enter the size of the arrayn”);
5. scanf (“%d”, &n);
6. int array[n];
7. printf (“Enter the elementsn”);

How do you find the largest number in an array without sorting?

No need to sort, just iterate through the array, keeping track of the largest value seen so far and the index of that value. var largest = -1; var player = -1; for (var i = 0; i < allPlayers. Length; ++i) { if (allPlayers[i] > largest) { player = i; largest = allPlayers[i]; } } Console.

What is the first largest number?

Googol. It is a large number, unimaginably large. It is easy to write in exponential format: 10100, an extremely compact method, to easily represent the largest numbers (and also the smallest numbers). With the smallest of effort, you can also present it in the full format: a “one” followed by one hundred “zeros”.

How do you find the second largest number in C?

Logic to find second largest element

Declare two variables max1 and max2 to store first and second largest elements. Store minimum integer value in both i.e. max1 = max2 = INT_MIN . Iterate though all array elements, run a loop from 0 to size – 1 . Loop structure should look like for(i=0; i<size; i++) .

How do you find the second smallest number in an array?

Let’s see another example to get second smallest element or number in java array using Arrays.

1. import java.util.*;
2. public class SecondSmallestInArrayExample1{
3. public static int getSecondSmallest(int[] a, int total){
4. Arrays.sort(a);
5. return a[1];
6. }
7. public static void main(String args[]){
8. int a[]={1,2,5,6,3,2};

How do I find the second largest element in a list Python?

Python Program to Find the Second Largest Number in a List

1. Take in the number of elements and store it in a variable.
2. Take in the elements of the list one by one.
3. Sort the list in ascending order.

How do you find the largest and smallest number in an array?

Algorithm to find the smallest and largest numbers in an array

1. Input the array elements.
2. Initialize small = large = arr[0]
3. Repeat from i = 2 to n.
4. if(arr[i] > large)
5. large = arr[i]
6. if(arr[i] < small)
7. small = arr[i]
8. Print small and large.

What is the second largest number in the world?

Googol: A very large number! A “1” followed by one hundred zeros. Googolplex: The world’s second largest number with a name. A “1” followed by a googol of zeros.

How do you find the second largest number with 3 numbers?

One more way to find the second maximum value among the 3 given values is to add all three numbers and remove the maximum and minimum values. Here max() and min() are the functions to find maximum and minimum values among 3 numbers respectively.

Which function finds the largest number in a range?

Example

How do you find the maximum difference in an array?

The task is to find the maximum difference between two elements such that the larger element appears after the smaller number. That is Arr[j]-Arr[i] is maximum such that j>i. Arr[] = { 2,1,3,8,3,19,21}. Explanation − The maximum difference is between 21 and 1 and 21 appears after 1 in the array.

How do you find the largest number in an array in Python?

PROGRAM:

1. #Initialize array.
2. arr = [25, 11, 7, 75, 56];
3. #Initialize max with first element of array.
4. max = arr[0];
5. #Loop through the array.
6. for i in range(0, len(arr)):
7. #Compare elements of array with max.
8. if(arr[i] > max):
