10 questions to make programming interviews less expensive -- Reference

about how to add or remove elements from linked list, because I believe that as a programmer you must know array, linked list, set, MAP and string algorithms. if you want to add another level of cushion than you can also ask about how to remove duplicates in array without using any library function. this will give you enough idea whether to proceed further or not. I knowTrivia is not a good way to find a programmers, But questions which are closely

RUBY: finding the largest number of Adjacent Elements in the array and solving the programming Pearl

Ruby calculates the maximum sum of Adjacent Elements in the array. Wei renyan 2010.8.21 I recently studied programming Pearl River and was very interested in the questions raised in the book. So according to the description in the book, I used Ruby to solve the related problems. The problems I learned today are as follows: This is a problem in Chapter 8th of programming

[Programming question] Find the minimum k Elements

5. Find the minimum k elements (array)Question: Enter n integers and output the smallest k integers.For example, if you enter the 8 numbers 1, 2, 3, 5, 6, 7, and 8, the minimum four digits are 1, 2, 3, and 4. The algorithm has learned the O (n) algorithm for finding small k elements. I tried to implement the following: Note that the new method initializes two-dimensional arrays. int (* a)[5] = new int[8][5
