Test Questions: 1. Sum TotalSpeed given data is degree and speed according every degree and it can solve by MAP with respected key(Degree) and value(Speed). 2. Remove Special Character and also number and also every first char is capital Input -> String[] words = {"hello!", "world@", "java#", "programming$", "is^fun"}; Output -> {Hello, World, Java, Programming, is, Fun} 3. sort the array and shift the all zeros in last. 4. Adjust Array means array given and you have to tell the highest number of array and adjust those less number then highest number in way that if we sum answerer should be highest number Adjusted Array: 3 6 0 0 9 4 5 Before Sum: 9, After Sum: 9 5. write the program for the loan management like 4000 loan fixed amount is 10%(400) and with 3% interest and remaining balance like second month 3600 interest will charged on that amount. ------------------------------------------------------------------- In interview they will asked LeetCode questions, at least first 50 questions of easy and hard. -> Unbalanced/ Balanced bracket ()}, {()} -> Remove duplicates from array (Two Pointer) -> Reverse whole statement not character -> Middle element of the linked List and data is in singly linked List

3rd Interview, onsite : -code a class that represent a rectangle -given a point, determine if its inside that rectangle -draw a binary tree of 3 levels -Code a class to represent a binary tree -write a function to count number of nodes in a binary tree -how does insertion and retrieval work in a BST ? whats the running time -define Big(O) notation -write a class to represent a linked list -how to discover if there's a loop in the linked list ? -given a phrase, reverse words i.e: "I want to eat" becomes "eat to want I" -given a phrase, find first non repeating character -whats agile -some behavioral questions
