Given an array of integers, find if the array contains any duplicates. Your function should return true if any value appears at least twice in the array, and it should return false if every element is distinct. To find the the required result.

We can put the integers in a hash table. Followup: Given an array of integers, find out whether there are two distinct indices i and j in the array such that the difference between nums[i] and nums[j] is at most t and the difference between i and j is at most k.

Given an array of integers, every element appears twice except for one. Find that single one. Note: Your algorithm should have a linear runtime complexity. Could you implement it without using extra memory? Bit manipulation. So we can go through the whole array and use the xor to get the only one. Skip to content Given an array of integers, find if the array contains any duplicates. Analysis: Simply put the values in a set. Then check the size of the set equals to the length of th array.

If a cell is not a sink, you may assume it has a unique lowest neighbor and that this neighbor will be lower than the cell.

Cells that drain into the same sink — directly or indirectly — are said to be part of the same basin. Your challenge is to partition the map into basins. In particular, given a map of elevations, your code should partition the map into basins and output the sizes of the basins, in descending order.

Assume the elevation maps are square. Input will begin with a line with one integer, S, the height and width of the map. The next S lines will each contain a row of the map, each with S integers — the elevations of the S cells in the row.

Some farmers have small land plots such as the examples below, while some have larger plots. If you try to view the sample inputs on a windows machine with a program that does not convert line endings like Notepadyou will see the input appear all on a single line.

Your code should output a space-separated list of the basin sizes, in descending order. Trailing spaces are ignored. While correctness and performance are the most important parts of this problem, a human will be reading your solution, so please make an effort to submit clean, readable code.

In particular, do not write code as if you were solving a problem for a competition. Given a list of points "x y", print "YES" if there exists a line containing 4 of the points, otherwise print "NO". Skip to content.

Latest commit Fetching latest commit….With the uptick in high-profile data breaches, organizations with large networks are working hard to guard against advanced intruders who identify and exploit complex vulnerabilities on the most important systems.

But often, a tunnel vision focus on sophisticated attacks distract organizations from more basic problems, like stale passwords or machines that haven't been patched against months-old vulnerabilities, that leave them just as vulnerable to attack. Solutions designed to guard against complex attacks generate an overwhelming number of alerts, requiring a large workforce to triage a flood of false positives.

These solutions don't solve the fundamental problems of security hygiene, which is, at its core, a data problem. Palantir Foundry helps organizations build a comprehensive, real-time view of their networks, then use that view to identify where the risk lives and who within the organization is accountable for mitigating it.

With Palantir Foundry, our clients are taking targeted actions to strengthen their security posture by:. Palantir Foundry represents a return to security first principles: count your doors, make sure they're locked, and prioritize your most valuable assets.

By creating a comprehensive, dynamic view of a network in Palantir Foundry, organizations can implement and strengthen basic cybersecurity hygiene practices—and from there, monitor activity for more complex attacks.

To perform a "flood fill", consider the starting pixel, plus any pixels connected 4-directionally to the starting pixel of the same color as the starting pixel, plus any pixels connected 4-directionally to those pixels also with the same color as the starting pixeland so on. Replace the color of all of the aforementioned pixels with the newColor. File Here! Discuss Flood Fill. At the end, return the modified image.

Note the bottom corner is not colored 2, because it is not 4-directionally connected to the starting pixel. Note: The length of image and image[0] will be in the range [1, 50]. The value of each color in image[i][j] and newColor will be an integer in [0, ].

The map was created using a hydrologic and hydraulic computer model, utilizing a digital elevation model created from LiDAR data and information on existing City-owned infrastructure. The model's calculations take into account projected sea level rise and storm surge causing elevated bay levels.

The maps are based on model outputs and do not account for future conditions such as new construction, City infrastructure upgrades, or other changes that may affect flooding. Although care was taken to capture relevant topographic features and structures in the City, site specific conditions such as property-line solid walls and fences may not be accounted for.

The map will be updated as needed to reflect changes in the City's infrastructure and urban land uses. This map does not provide flood risk information for those areas. Finally, this map shows flood risk from storm runoff only.

Palantir is an algorithm to align cells along differentiation trajectories. Palantir models differentiation as a stochastic process where stem cells differentiate to terminally differentiated cells by a series of steps through a low dimensional phenotypic manifold.

Palantir effectively captures the continuity in cell states and the stochasticity in cell fate determination. Palantir has been designed to work with multidimensional single cell data from diverse technologies such as Mass cytometry and single cell RNA-seq. Palantir depends on a number of python3 packages available on pypi and these dependencies are listed in setup.
