In Array find largest second number ?

5 respuestas

Can,t we do sorting from largest to smallest give arr[1] which is of course second largest Menos

It Took Time but Simple logic is needed.

Would be impressive to solve the general case... find the kth large number: create a minheap of size k, and for each element in the array, if that number is bigger than the top of the minheap, replace the top of the minheap with that number and recreate the minheap. Running time is O(nlgn). If you can have negative numbers, then you can easily modify this code. int findKthLargestNumber(int[] A, int k) { if (k minHeap[2*i+1]) { int temp = minHeap[i]; minHeap[i] = minHeap[2*i+1]; minHeap[ 2*i+1] = temp; i = 2*i+1; } else if (minHeap.length minHeap[2*i+2)]) { int temp = minHeap[i]; minHeap[i] = minHeap[2*i+2]; minHeap[ 2*i+2] = temp; i = 2*i+2; } else { done = true; } } Menos

String replacement on coderpad. More of pair programming , with hints that helped a lot.

4 respuestas

I thought out loud the whole time, almost everything was hints, otherwise it was a tough problem. Menos

When was your interview? 13th?

Can you elaborate on String replacement problem? Currently studying for other interviews and was wondering what this was like. Thanks! Menos

Given 100 white marbles and 100 black marbles and two jaws. Put these marbles in the two jars in a way that would maximize the chance of retrieving a white marble from any given jaw.

4 respuestas

Really that is what you would answer? What if they stirred the jars around after you distributed the marbles? Personally I think a better answer is to put 1 white marble in the first far and 99 white marbles and 100 black marbles in the second jar. If you choose the jar at random you now have a 74.87% chance of getting a white marble, regardless of the marbles position in the jar. Menos

qq is right, that is the optimum combination.

2 colours, 2 jars. White in one, black in the other

Why the potholes have circular opening?

4 respuestas

Because if its square, the lid can easily slip inside along the diagonal. length of diagonal is greater than side of square. Menos

1. Easy to roll 2. comparison to other shapes, distributes weight along sides easily :) Menos

Given a string determine if it consist of valid concatenated words. "dogcatfish" --> true because it can be split int "dog","cat", and fish "dogecatfish" --> false

the above solution is ok for small dictionary... it is not time or space efficient... typically this problem is solved using dynamic programming... for the purpose of the interview, I am not sure if the above is acceptable Menos

DP is perfect solution for the above question. Normally, DP will be asked to optimize the solution of recursive one. Menos

1.difference between abstract class,interface

4 respuestas

abstract class is contain abstract methods as well as concreat methods where as interface contain only abstract methods Menos

Interface is a service recuirments specification which describes the services offered. And it is 100% abstract class. If we don't want to allow a program to create an object for a class, then declare that class as abstract class. Methods in abstract class are may or may not abstract methods. Menos
