Quick Answer: How do you find the smallest and second smallest element in an array?

Contents

A simple way to find the smallest and second smallest element is that sort the array in ascending order and pick its first and second elements. Its first element will be the smallest number and the second number will be the second smallest number. The time complexity of this solution is O(n log n).

How do you find the minimum and second of an array?

Let’s see the full example to find the second smallest number in java array.

public class SecondSmallestInArrayExample{
public static int getSecondSmallest(int[] a, int total){
int temp;
for (int i = 0; i
{
for (int j = i + 1; j
{
if (a[i] > a[j])

How do you find the smallest element in an array?

Algorithm

STEP 1: START.
STEP 2: INITIALIZE arr[] = {25, 11, 7, 75, 56}
STEP 3: min = arr[0]
STEP 4: REPEAT STEP 5 for(i=0; i
STEP 5: if(arr[i]
STEP 6: PRINT “Smallest element in given array:”
STEP 7: PRINT min.
STEP 8: END.

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

Algorithm to find the smallest and largest numbers in an array

Input the array elements.
Initialize small = large = arr[0]
Repeat from i = 2 to n.
if(arr[i] > large)
large = arr[i]
if(arr[i]
small = arr[i]
Print small and large.

Java Array: Exercise-41 with Solution

The smallest element is -8 and second Smallest element is 1.

What is the smallest element?

Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

How do you find the first two minimum values of an array?

A Simple Solution is to sort the array in increasing order. The first two elements in sorted array would be two smallest elements. Time complexity of this solution is O(n Log n). A Better Solution is to scan the array twice.

How do you find the greatest element in an array?

To find the largest element, the first two elements of array are checked and the largest of these two elements are placed in arr[0] the first and third elements are checked and largest of these two elements is placed in arr[0] .

What is kth smallest element?

kth smallest element is the minimum possible n such that there are at least k elements in the array n. You are not allowed to modify the array ( The array is read only ).

How do you find the minimum of an array in C++?

using namespace std;
int main()
int arr[] = { 4, 2, 1, 6, -8, 5 };
int min = INT_MAX, max = INT_MIN;
for (int i: arr)
if (i min) {
min = i;
if (i > max) {

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

Find 2nd Largest Number in Array using Arrays
