how to find maximum number in array till a particular index 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: find the maximum number from an int Array

---without sort method---
public static int maxValue( int[]  n ) {

int max = Integer.MIN_VALUE;

for(int each: n)

if(each > max)

max = each;

 
return max;
  
---with sort method---
public static int maxValue( int[]  n ) {

Arrays.sort( n );

return  n [ n.lenth-1 ];

}
