I attended a programming competition(it has ended now). I don't know why my solution is giving WA, I read the editorial, saw other people solution but unable to find a flaw in my solution. Obviously I am missing somewhere. Please help! Question Link

I'm trying to make a program to check whether the word "nadia" is present with this sequence in a string. if you can delete zero or more characters to get this word then you should print "YES" else print "NO". Can anyone help

Given an array with any size, in my case the array size is 5. This array contains ALL numbers from 1 to 5 (must contain all of them) [1 | 2 | 3 | 4 | 5] 0 1 2 3 4 And now, one element was reset and was set to 0, and the mission is to find what number

Let's say I have a 500x500 2D grid (from -250 to 250). Each cell of the grid has a certain value, from 0 to 100. What I've been trying to do is keep a list of all the cell with a value lower than 50 starting at the point (0, 0), but I would like not

I have a requirement in one of my J2EE project, where I have to pre-process data based on some business logic and formulate it into data structure (may be in memory database table) so I can use result by keeping look up into that data structure for p

I'm writing a program that reads a general HTML "article" page (Wikipedia, NY Times, Yahoo News, ect). From that page I want to strip away all of the "noise" (ads, header bars.. anything that isn't part of the article content.) To thin

I have a long string 'str' and a list of a triplets in the form [start, end, replace_str]. I need to iterate through the list of triplets and replace the contents of 'str' between start and end indices by replace_str. The replace_str string can be of

I have a code that generates all of the possible combinations of 4 integers between 0 and 36. This will be 37^4 numbers = 1874161. My code is written in MATLAB: i=0; for a = 0:36 for b= 0:36 for c = 0:36 for d = 0:36 i=i+1; combination(i,:) = [a,b,c,

There was a problem in cracking the coding interview -part V Question 11.7 and the solution I am trying to implement here is their solution in Java converted to C++.But I am facing issue of segmentation fault. #include<iostream> #include<vector&g

Say we have two english texts T1 and T2 (disjoint no overlap ) cut out from a larger text T. Is there a way to figure out that T1 and T2 came from a single larger text? For example , newspaper layout is in multi column text. Given two column of text

I'm trying to find a suitable DP algorithm for simplifying a string. For example I have a string a b a b and a list of rules a b -> b a b -> c b a -> a c c -> b The purpose is to get all single chars that can be received from the given string

I have a grid (an NSArray of CGPoints)where I want to layout some objects at points based on some constraints. This is what I know: How big the grid is The number of objects that have to be laid out on the grid, at a point The minimum distance betwee
