Intersection of two numerical arrays
Return the max k numbers from an unsorted integer array. Each number in the array is in the range [0, 10000).
Question was "Given a pattern and a string input - find if the string follows the same pattern and return 0 or 1. Examples: 1) Pattern : "abba", input: "redblueredblue" should return 1. 2) Pattern: "aaaa", input: "asdasdasdasd" should return 1. 3) Pattern: "aabb", input: "xyzabcxzyabc" should return 0. I saw someone else had a similar question, but it was much much easier as the other candidate was given spaces between words to help identify individual words to pattern match.
If you were building a search tool and wanted search results to pop up as you typed but the server call was taxing, write a function that gets called on every key down but calls the server when the user stops typing for 400ms.
find the largest sum of consecutive integers in an array
Implement a function for determining the validity of a string. The string is valid if parentheses are correctly distributed within the string.
Just leave a message here with the questions & I will post the solution in 5-10 minutes if I have got the same questions or I will write the solution if I know it. I got 3 coding problems to be done 90 minutes.
PHONE : 1. Pass by value/ pass by reference. Write a function to swap 2 variables - ll u use pass by value or reference ? 2. Do the same to swap 2 objects (how does it change) 2. Detect 11010 sequence with moore and mealy state machines. 3. Use of const ? What ll happen if you declare above 2 objects as const. 4. Explain NB assignment and blocking assignment. About event regions. 5. Fibonacci -- iterative solution and recursive solution. 6. Disadvantages of a recursive solution. 7. Output of this code fragment : reg a,b,c,d,w; assign w = a; initial begin a = 2; c=5; b<=c; a=5; end what is output of all registers. 8. Explain RISC pipeline. What is the problems. 9. Explain about uvm driver etc. ONSITE : round 1: Round Robin Arbiter Design round 2 : (1) Given a stack class implementation (LIFO) - there are 3 methods - push(), pop(), isempty(). Write a class using objects of given class to implement a FIFO. (2) Make best performance Implement the dist functionality in c++. Given a set of weights mimic to provide randomization skewed to the specification (Basically, write a function that would do something similar to a 'dist' in system verilog). round 3 : Given a divide by 3 state machine. Implement a divide by 5 statemachine. How many vectors are needed to verify it. So the circuit takes serial bit inputs and asserts if the number is a multiple of 3 or 5. round 4 : Circuits project. Basic pipeline architecture. Design a pipeline for a histogram processor. In every cycle we get an instruction (CLR, ADD INCR). Handle dependencies using bypass. round 5 : Given a producer and consumer. They are clocked with the same clock. Producer produces 80 writes for 100 clocks (no random). Consumer reads 8 times per 10 clocks. Find the FIFO depth. Write RTL and verify.
Write a function in language of your choice that takes in two strings, and returns true if they match. Constraints are as follows: String 1, the text to match to, will be alphabets and digits. String 2, the pattern, will be alphabets, digits, '.' and '*'. '.' means either alphabet or digit will be considered as a "match". "*" means the previous character is repeat 0 or more # of times. For example: Text: Facebook Pattern: F.cebo*k returns true
