How do you find the largest and smallest number in an unsorted integer 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.

Assume first array element as maximum and minimum both, say max = arr[0] and min = arr[0] . 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 .

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 smallest number in an array?

Java program to find the smallest number in an array

  1. Compare the first two elements of the array.
  2. If the first element is greater than the second swap them.
  3. Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.
  4. Repeat this till the end of the array.

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

If we sort the array in ascending order, the kth element of an array will be the kth smallest element. To find the kth largest element, we can pass k= length(Array) – k.

How do you find the maximum value in an array?

Java program to find largest number in an array

  1. Initialize array value.
  2. Step 2: (int max = a[0];) Initialize max value as array’s first value.
  3. Step 3: (for int i = 1; i < a.length; i++ ) …
  4. Step 4: if(a[i] > max)
  5. Continue the loop and resign the max value if array current value is greater than max.
  6. Program. …
  7. Output.

How do you find the maximum and minimum of a function?

HOW TO FIND MAXIMUM AND MINIMUM VALUE OF A FUNCTION

  1. Differentiate the given function.
  2. let f'(x) = 0 and find critical numbers.
  3. Then find the second derivative f”(x).
  4. Apply those critical numbers in the second derivative.
  5. The function f (x) is maximum when f”(x) < 0.
  6. The function f (x) is minimum when f”(x) > 0.

How do you find the largest number in an array C++?

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

How many comparisons are required to find the maximum and minimum?

Ans: minimum number of comparison require to find minimum and maximum is: Approach is divide and conquer …. Thus, the approach does (3/2)n−2 comparisons if n is a power of 2. And it does more than (3/2)n−2 comparisons if n is not a power of 2.

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

The program output is shown below.

  1. #include<iostream>
  2. int arr[10], n, i, max, min;
  3. cout << “Enter the size of the array : “;
  4. cin >> n;
  5. cout << “Enter the elements of the array : “;
  6. for (i = 0; i < n; i++)
  7. cin >> arr[i];
  8. max = arr[0];

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;

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.

Which is the smallest whole number?
