Find second largest number in set Program Code

# Find second largest in set
numbers = {74, 18, 93, 35, 61, 26, 82, 49}
print("Set:", numbers)

# Method 1: Using sorted
sorted_unique = sorted(numbers)
if len(sorted_unique) >= 2:
    print(f"Second largest: {sorted_unique[-2]}")

# Method 2: Single pass
largest = second = float('-inf')
for num in numbers:
    if num > largest:
        second = largest
        largest = num
    elif num > second and num != largest:
        second = num
print(f"Single pass: {second}")
