Onsite interview 1: A paper test, questions including Java syntax, SQL, JavaScript, code review. Java syntax question is: given a method: int exchange(int a), we need: if a == 1 return 2, if a == 2 return 1. Give 4 methods to implement the method, "if" statement cannot be used. SQL question was about nested queries and aggregation. JavaScript question was to write a JavaScript function, when a radiobox is checked then alert sth. Code review question is an implementation of tree level traverse algorithm, lot of errors.
Sigiloso
can be done using ternary operator int result = (input == 1) ? 2 : 1 ; return result ;
