. In this **Leetcode** Single Number problem solution, we have Given a non-empty array of integers nums, every element appears twice except for one. Find that single one. You must implement a solution with a **linear** runtime complexity and use only constant extra space. Problem solution in Python.

piecewise **linear** function and the explanation . Tue 22 September 2015. Suppose the data is generated in this way: x is from random normal with mean 0, std = 10. length of x is 1000. if x < -15, then y = -2 · x + 3. if -15 < x < 10, then y = x + 48. if x < 10, then y = -4 · x + 98. We can rewrite the above funcion in the following way:.

Given two strings X and Y, the supersequence of string X and Y is such a string Z that both X and Y is subsequence of Z. in other words shortest supersequence of X and Y is smallest possible string Z such that all the alphabets of both the strings occurs in Z and in same order as of the original string. X = "opengenus" Y = "operagenes" shortest. 3.67/5 (2 votes) 6 Jan 2015 CPOL 4 min read. **Solving Word-Search Puzzles in Linear Time**. The word-search puzzle is a string-search problem in which several words are to be located within an n ´ m array filled with letters. The following table shows a 30 ´ 30 array and some words that must be found in it. Each word must occur entirely in a row. The Dynamic **Programming** Solution — O(n): Again, since the length of the nums array will be used multiple times, save that into a variable. Then check for corner cases, if the length is 1 then.

Buy **LeetCode** premium. Go through all the questions under the "Apple" tag, and solve all Easy ones before jumping on Medium ones. This was my plan for the next eleven days. I followed half of it,. Although the model is widely used for multi-objective **linear programming** problems based on computational and results, we still limit ourselves to using WOA to solve this constraint as more. Steps in detail. Step 1: Initialize a hashmap with characters as key and their frequency as the value. Hashmap format Hashmap<char,int>. Step 2: Iterate the string - calculate the frequency of each character with the help of hashmap. Step 3: After the first iteration we will have a hashmap of with character of string along with their frequency.

Examples: If given points are (-1, 3), (4, 3), (2, 1), (-1, -2), (3, -3) and (xO, yO) point is (1, 0) i.e. every line must go through this point.

Algorithm Design and Analysis--**Linear**.These two lines are represented by the equation a1x + b1y + c1= 0 and a2x + b2y + c2 = 0, respectively. Given figure illustrate the point of intersection of two lines. We can find the point of intersection of three or more lines also. By solving the two equations, we can find the solution for the point of intersection of two lines.
