## How do you find the largest and smallest number?

There are several ways to calculate the smallest or largest number in a range.

Example.

A
Formula Description (Result)
=MIN(A2:A7) Smallest number in the range (0)
=MAX(A2:A7) Largest number in the range (27)

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

1) Declare/provide input array 2) Initialize max and min numbers to some random numbers in array, let’s say inArray 3) Traverse through the array 3.1) Check if the current element is greater than the max, if yes then set max to current element.

## How do you find the smallest digit of a number in Java?

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

1. import java.util.*;
2. public class SmallestInArrayExample1{
3. public static int getSmallest(int[] a, int total){
4. Arrays.sort(a);
5. return a;
6. }
7. public static void main(String args[]){
8. int a[]={1,2,5,6,3,2};

## How do you find the smallest number?

To get the smallest number, we arrange the digits in ascending order. 2 < 5 < 7 < 8. The smallest number using the digits 7 5 2 8 is 2578.

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

Find 2nd Largest Number in Array using Collections

1. import java.util.*;
2. public class SecondLargestInArrayExample2{
3. public static int getSecondLargest(Integer[] a, int total){
4. List<Integer> list=Arrays.asList(a);
5. Collections.sort(list);
6. int element=list.get(total-2);
7. return element;
8. }

## What is the largest number Java can handle?

The int type in Java can be used to represent any whole number from -2147483648 to 2147483647. Why those numbers? Integers in Java are represented in 2’s complement binary and each integer gets 32 bits of space.

## How do you find the average of an array?

Average is the sum of array elements divided by the number of elements. Examples : Input : arr[] = {1, 2, 3, 4, 5} Output : 3 Sum of the elements is 1+2+3+4+5 = 15 and total number of elements is 5.

## Which is the smallest whole number?

The smallest whole number is “0” (ZERO).

## What is greatest and smallest number?

Thus, the greatest number is 8741. To get the smallest number, the smallest digit 1 is placed at thousands-place, next greater digit 4 at hundred’s place, still greater digit 7 at ten’s place and greatest digit 8 at one’s or units place. Thus, the smallest number is 1478.

## What is a smallest number?

0 is the smallest whole number. W = {0,1,2,3,4… } 1 is the smallest natural number. N = {1,2,3,4…..

## How do you find the maximum and minimum of an array?

Logic to find maximum and minimum element in array

Assume first array element as maximum and minimum both, say max = arr and min = arr . Iterate through array to find maximum and minimum element in array. Run loop from first to last array element i.e. 0 to size – 1 .
