how to get the highest integer in arr code example

Example 1: Write a function that returns the largest element in a list

def return_largest_element(array):
    largest = 0
    for x in range(0, len(array)):
        if(array[x] > largest):
            largest = array[x]
    return largest

Example 2: max element in array

int max;
max=INT_MIN;

for(int i=0;i<ar.length();i++){
	if(ar[i]>max){
    	max=ar[i];
    }
