Please see our Community Guidelines or Terms of Service for more information. Reliability Test, Stability Test, UI Test, Platform Test, Also include, performance, stress & load testing, Accessibility, user experience, globalization, localization, integration, compatibility. Make sure you to ask different questions and confirm the type of tree. How about traversing from one node to root, adding each node to hashset, Then try do the same with second one, on collision return node. Written in python. Stress testing has been a huge part of my job in past positions.". An agreed acceptance criterion is usually discussed with the customer, which involves points to meet in order to accept a software product. The binary search tree property says that there CAN be duplicates: "Let x be a node in a binary search tree. "Hello world" becomes "world Hello". Rarely has the testing environment been set up improperly, but that has happened before as well. Here’s Exactly What to Write to Get Top Dollar, How To Follow Up After an Interview (With Templates! static void FindPairs(int sum) { for (int i=-50; i=-50) { Console.WriteLine(i + " " + otherNum); } } }, Solution with no duplicates: @Test public void findPairsTest() { // TestCases // Alternately you can put this test cases in dataprovdier findPairs(50); findPairs(20); findPairs(-20); findPairs(-50); findPairs(0); } private void findPairs(Integer sum) { HashMap inputPair = new HashMap(); HashMap outputPair = new HashMap(); for(int i=-50; i<=50; i++) { inputPair.put(i, sum-i); } // print pairs for(Integer key : inputPair.keySet()) { Integer potentialOtherNum = inputPair.get(key); if(inputPair.containsKey(potentialOtherNum) && potentialOtherNum < key) { outputPair.put(key, potentialOtherNum); } } System.out.println(outputPair.entrySet().toString()); }, Use two pointers, one at the begin, one at the end, let us call the pointer begin and end, the array is named nums. typedef pair Pair; list l; //create an empty list of tuples pairofsum(l,10); // an example of how to call the function which adds to your list of tuples the possible pairs of the sum void pairofsum(list& l,int sum) { if(sum==0) { Pair p; loadPair(p,0,0); l.push_back(p); for(int i=1;i<51;i++) { loadPair(p,i, -i); l.push_back(p); } } else if (sum<0) { Pair p; for(int i=0;i+-sum<51;i++) { loadPair(p,i,-(i+-sum)); l.push_back(p); } for(int i=1;i<=-sum/2;i++) { loadPair(p,-i,sum+i); l.push_back(p); } } else { Pair p; for(int i=1;sum+i<51;i++) { loadPair(p,-i,sum+i); l.push_back(p); } for(int i=0;i<=sum/2;i++) { loadPair(p,i,sum-i); l.push_back(p); } } } void loadPair(Pair& p, int f, int s) { p.first=f; p.second=s; }, Here is my C# implementation. Have you ever been part of a quality assurance team? Understanding the questions that an interviewer might ask can help you prepare your answers for your software testing interview. Answer: What hobbies do you have besides software testing? In other words, the value of a child node may be equal to the value of a parent node, which would yield the result that "Interview Candidate" posted on Mar 14 2012. *; import java.util. // returns null for a new entry // returns the index if it previously if it existed Integer initialOccurence = charsMap.put(characters[index], index); if ( initialOccurence != null) { return initialOccurance; } //there where no characters that where duplicates return -1; } }, Another python solution: def findFirstNonRepeatedCharInOneIteration(str1): for i,j in enumerate(str1): if j in str1[:i] or j in str1[i+1:]: print "First non-repeated character is "+ j break str1 = "abcdefglhjkkjokylf" findFirstNonRepeatedCharInOneIteration(str1), function getFirstDuplicateCharacter(str) { const seen = new Set(); for (const char of str) { if (seen.has(char)) return char; seen.add(char); } }, import java.io. You might consider listing the software tests you have performed before as well as other software tests you know about. Depending on the company, an interviewer might ask you questions based on code fragments, so it is beneficial to understand how to read and interpret software code. O(n). Then travel upwards from that position. A complete binary tree is a tree in which all nodes have the same depth. A software testing interview may contain general questions, questions about your experience and background in software testing and in-depth questions that reveal your understanding of specific testing processes. Now you do a second pass, and for each number, you look at the number at index T-i-50. The fact is ttttttt t t. T to t. To. There are several steps associated with a test planning activity. Because everything left is less than and everything right is greater than, we can traverse the tree using this knowledge. = null) { temp = temp.parent; counter1++; } temp = node2; while( node2.parent ! Can you explain what you would include in a test report? Before going ahead, let’s see some unavoidable Interview Questions which every hiring manager asks you in any Software Testing interview.

Answer: Current progress of testing can be reported thereafter by all testers responsible for their feature. What are your biggest strengths in testing? Software testers are responsible for identifying defects in software products and therefore must be well-versed in computer programming. ), 7 of the Best Situational Interview Questions. It can help cut down the number of test cases, by recognizing the different sets of data which are unique, and only executing test from each set of data. Consider speaking about the general process that could be related to most software tests as well as your understanding that each test will contain different steps. Answer: Then you loop through the array, and drop each number i in cell of index i-50. Binary Search tree is a storage data structure that allows log(n) insertion time, log(n) search, given a balanced binary search tree. temp1 = node1; temp2 = node2; while( temp1.parent != null && temp2.parent != null){ if(temp1.value == temp2.value){ return temp1; // temp1 and temp2 point to same node so pick one } temp1 = temp1.parent; temp2 = temp2.parent; } System.out.println("no such ancestor"); Consider this is a BST, where max node is always on the right of min node, we can traverse max upward one node at a time while comparing min nodes as it traverse upward toward root. Once testing is being done, exit reports can be produced by respective testers with their functionalities. What do you dislike most about software testing?
