How do you find the largest number in an unsorted 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 best way to find the largest number in an array?

To find the largest element,

1. the first two elements of array are checked and the largest of these two elements are placed in arr[0]
2. the first and third elements are checked and largest of these two elements is placed in arr[0] .
3. this process continues until the first and last elements are checked.

What is the largest number of comparisons required by linear search performed on an unsorted array of size n?

The maximum number of comparisons performed by the linear search on an array of N elements is N/2(assuming values are consistently found).

Which algorithm finds the largest number first?

In a selection sort, the first process in the algorithm is to find the data element that has the largest value.

Which sorting algorithm finds the largest element in an unsorted list and places it into its correct position during each pass?

bubble sort
As explained above, bubble sort is structured so that on each pass through the list the next largest element of the data is moved to its proper place. Therefore, to get all n elements in their correct places, the outer loop must be executed n times.

What will be the most efficient approach to find the largest number in a list of twenty number?

See the leftmost digit of the numbers given. The digit with highest left most digit is largest number. If there are more than one numbers with same leftmost digit, Then see the second leftmost digit of these numbers, the number with highest number at second left place will be largest.
