Python Program to find largest element in an array

In this article, we will learn about the solution and approach to solve the given problem statement.

Problem statement

Given an array as an input, we need to find the largest element in the array.

Approach

• We initialize max as the first element.
• After this, we traverse the given array from the second element till end.
• For every traversed element, we compare it with the current value of max
• if it is greater than max, then max gets updated.
• Otherwise, the statement surpasses

Let’s see the implementation below −

Example

def largest(arr,n):
   #maximal element
   max = arr[0]
   for i in range(1, n):
      if arr[i] > max:
         max = arr[i]
   return max
# main
arr = [10, 24, 45, 90, 98]
n = len(arr)
Ans = largest(arr,n)
print ("Largest in the given array is",Ans)

Output

Largest in the given array is 98

All the variables and functions are declared in global scope as shown in the figure below.

Conclusion

In this article, we learned about the approach to find the largest element in an array.
