Study Notes
Python Lambda Function
- The output of the given Python code is
Welcome to Ixambee. - The
lambdafunction is used to define a small anonymous function.
Algorithm Approach
- Greedy Algorithm focuses on finding a local optimum solution.
- Dynamic Programming also focuses on finding a local optimum solution.
Binary Search Tree (BST) Traversal
- The in-order traversal of a BST with the given pre-order traversal is
60 70 80 150 200 250 350. - In-order traversal visits the left subtree, then the current node, and finally the right subtree.
SQL Delete Query
- The correct version of a delete query in SQL is
DELETE FROM table_name WHERE condition;. - The
DELETEstatement is used to delete records from a table. - The
WHEREclause is used to specify which records to delete.
Arrays in C Language and R
- Arrays in C language and R are similar in that they are used to hold data values of the same type.
- Both support multidimensional arrays.
- However, arrays in C language cannot dynamically resize, whereas arrays in R can.
- The syntax for accessing elements in arrays is similar in both C language and R.
