Find maximum value in dictionary Program Code

# Find maximum value in dictionary
scores = {"Java": 82, "Python": 98, "C++": 88, "JavaScript": 94, "Rust": 90}
print("Dictionary:", scores)

# Method 1: Using max() on values
max_value = max(scores.values())
print(f"\nMaximum value: {max_value}")

# Method 2: Find key with maximum value
max_key = max(scores, key=scores.get)
print(f"Student with highest score: {max_key} = {scores[max_key]}")

# Method 3: Get both key and value
max_pair = max(scores.items(), key=lambda x: x[1])
print(f"Using items(): {max_pair[0]} → {max_pair[1]}")

# Method 4: Manual iteration
max_key_manual = None
max_val_manual = float('-inf')
for key, value in scores.items():
    if value > max_val_manual:
        max_val_manual = value
        max_key_manual = key
print(f"Manual method: {max_key_manual} → {max_val_manual}")
