There are N problems numbered N which you need to complete.

Problem Solving Technique #1 for Coding Interviews with Google, Amazon, Microsoft, Facebook, etc.

You've arranged the problems in increasing difficulty order, and the i th problem has estimated difficulty level i. You have also assigned a rating vi to each problem. Problems with similar vi values are similar in nature.

On each day, you will choose a subset of the problems and solve them. You've decided that each subsequent problem solved on the day should be tougher than the previous problem you solved on that day. Also, to make it less boring, consecutive problems you solve should differ in their vi rating by at least K. What is the least number of days in which you can solve all problems? The first line contains the number of test cases T.

T test cases follow. Each case contains an integer N and K on the first line, followed by integers v1, Output T lines, one for each test case, containing the minimum number of days in which all problems can be solved. For the first example, you can solve the problems with rating 5 and 7 on the first day and the problem with rating 4 on the next day. Note that the problems with rating 5 and 4 cannot be completed consecutively because the ratings should differ by at least K which is 2.

Also, the problems cannot be completed in order 5,7,4 in one day because the problems solved on a day should be in increasing difficulty level.

Helpful 2 people found this review helpful mike of Belton, MO Verified Reviewer Original review: Dec. Calling to cancel service. They tell me it has been over 30 days and have to do the early termination. Working with them to waive that as the issue is not my fault and the excessive install attempts were no fault of the customer. This is the absolute worst customer service I have ever experienced with anyone. I would not recommend this service to anyone at any price.

The excessive calls and transfers into their call centers are so time consuming and frustrating when you have to repeat all the information each time you are transferred and then they do not complete a install when they do come out. On two install attempts, the tech did not have any idea what the objective or problem he was there to solve was. I had to explain it, again, to the tech after repeatedly confirming with the customer service rep that all the correct information was included in the ticket.

Helpful Be the first one to find this review helpful Cliff and Katina of Mandan, ND Verified Reviewer Original review: Dec. So far, every month we are having to call in and dispute the monthly bill charges. I checked our online statement to see what this charge was about and we still do not know what this charge was for.

I cancelled the auto pay because we should not have to worry about what they are charging us. This 2-year contract is B. I am regretting switching to DirecTV. Helpful Be the first one to find this review helpful Janet of Brattleboro, VT Verified Reviewer Original review: Dec. I have spent many hours waiting to speak with them. Spoke with the fraud dept, they promised to resolve this and I am still being called telling me I have an outstanding bill.

Will it go to collections. All I know is I am feeling harassed for a service I never authorized. Helpful Be the first one to find this review helpful Joan of Breezewood, PA Verified Reviewer Original review: Dec. Of course, we did not know until credit card bill came. When we called, they said there was no record of cancellation.

Data Structures

After several calls, and being told not to pay the bill, we receive a letter from collection agency. I am very disappointed with them - we only want a fair deal. My credit back 2 years ago was not good, and I left some small refundable deposit. Sounds like a ripoff to me. Helpful 2 people found this review helpful Tiana of Marina Del Rey, CA Verified Reviewer Original review: Dec. I have called in many times and spent many countless hours on the phone with them and my issue is still unresolved.

They continuously keep repeating the same thing over and over to me even if it does not make sense.
