Problem 1: Three ways to sum to N

• Implemented 3 unique sum_to_n solutions: iterative loop O(n), recursion O(n), and arithmetic formula O(1)
• Each function includes a comment explaining the approach and time/space complexity
• Added a test() harness covering 10 cases (including edge cases like 0 and 1) that validates all 3 implementations against expected results

Problem 2: Three ways to sum to N

• Light mode

• Dark mode

Problem 3: Messy React

• Added missing blockchain property to WalletBalance interface
• FormattedWalletBalance now extends WalletBalance instead of duplicating fields
• Removed empty Props interface, use BoxProps directly
• Moved getPriority outside component and replaced switch with a Record lookup
• Changed blockchain: any to blockchain: string
• Removed unused children destructuring
• Fixed lhsPriority → balancePriority (undefined variable bug)
• Fixed inverted filter logic: now keeps amount > 0 instead of amount <= 0
• Sort comparator now returns 0 for equal priorities instead of undefined
• Removed unused prices from useMemo dependency array
• Wrapped formattedBalances in useMemo
• rows now maps over formattedBalances instead of sortedBalances
• Replaced key={index} with key={balance.currency}
• Replaced undefined classes.row with a plain className string
