Q2. Find total Nodes in a Binary tree along with time and space complexity
Ans. 
Total nodes in a binary tree can be found using depth-first or breadth-first traversal algorithms with time complexity O(n) and space complexity O(h), where h is the height of the tree.
• Use depth-first traversal (pre-order, in-order, post-order) or breadth-first traversal to visit each node and count the total nodes.

• Time complexity is O(n) where n is the number of nodes in the tree.

• Space complexity is O(h) where h is th...read more

Q3. How to compare 2 large 100 GB JSON files in O(1) Time complexity
Ans. 
Use hashing to compare the JSON files in O(1) time complexity.
• Create a hash function to convert the JSON data into a unique hash value.

• Calculate the hash value for each JSON file and compare the hash values.

• If the hash values are equal, the JSON files are identical.

• Example: Use MD5 or SHA-256 hash functions for generating hash values.

Q4. Map parent to children of a 4 Array tree in O(1) Space complexity
Ans. 
Use array indices to map parent to children in a 4 Array tree in O(1) space complexity.
• Assign children of a parent at indices 4*i+1, 4*i+2, 4*i+3, 4*i+4 where i is the index of the parent.

• To find parent of a child at index j, use (j-1)/4 to get the parent index.

Q1. How to analyse Banking Balance Sheet What are key ratios of NBFC/Bank
Ans. 
Analyzing a bank's balance sheet involves examining key ratios such as capital adequacy, asset quality, and liquidity.

• Examine asset quality by calculating non-performing asset (NPA) ratio

• Analyze liquidity by calculating loan-to-deposit (LTD) ratio

• Assess profitability by calculating return on assets (ROA) and return on equity (ROE) ratio...read more
