Maximal Square. Difficulty: Medium279 Perfect squares · LeetCode Solutions. 279. Perfect Squares. Given a positive integer n, find the least number of perfect square numbers (for example, 1, 4, 9, 16, ...) which sum to n. For example, given n = 12, return 3 because 12 = 4 + 4 + 4; given n = 13, return 2 because 13 = 4 + 9. Solution 1.Feb 25, 2019 · Consider a matrix M with dimensions width * height, such that every cell has value 0 or 1, and any square sub-matrix of M of size sideLength * sideLength has at most maxOnes ones. Return the maximum possible number of ones that the matrix M can have.

Quite an easy problem. We need to search for maximal k satisfying k^2 <= x, so we can easily come up with the solution ... The overwhelming advantage of binary search solution to heap solution is that it doesn't need to explicitly ...I am trying Leetcode Question - 69. Sqrt(x) Given a non-negative integer x, compute and return the square root of x. Since the return type is an integer, the decimal digits are truncated, and only the integer part of the result is returned. Note: You are not allowed to use any built-in exponent function or operator, such as pow(x, 0.5) or x ** 0.5.Detect Squares LeetCode Solution - You are given a stream of points on the X-Y plane.

If the number satisfies the conditions in the two square theorem (prime factors of the form 4k+3 appear with even multiplicity in prime factorisation) then the answer is 2. If the number satisfies the conditions in Legendre's three square theorem, (not of the form 4^a (8k+7)), then the answer ... 221. Maximal Square.
