Help me in solving SESO41 problem

My issue

explain my error what i need to do

My code

def selectionSort(arr):
    for i in range(len(arr)):
        # Assume the current index holds the smallest element
        min_index = i
        
        # Find the index of the smallest element in the remaining array
        for j in range(i + 1, len(arr)):
            if arr[j] < arr[min_index]:
                min_index = j
        
        # Swap the smallest element found with the element at the current index
        arr[i], arr[min_index] = arr[min_index], arr[i]
    return arr

# Input
n = int(input())
arr = list(map(int, input().split()))

# Perform Selection Sort
sorted_arr = selectionSort(arr)

# Output the sorted array
print(" ".join(map(str, sorted_arr)))
