1. The title asks for a sequence of n integers (possibly negative numbers) a[1],a[2],a[3],..., A[n], and the maximum value of the sub-segments of the sequence, such as A[i]+a[i+1]+...+a[j]. When the given integer is negative, define the sub-segment and 0, according to this definition, the optimal value is: Max{0,a[i]+a[i+1]+...+a[j]},1public class MaxArry { /** * @param args */ public static void main(String[] args) { // TODO Auto

In January 1995, Scott Meyers in the C + + magazine that "Min,max is a big challenge for the C + + community", he analyzed the Min,max based on macro-based, and compared min based on the template, Max implementation, he got the following conclusion: "What is the best way to achieve Max?" With a Tevye quote: "I will te

Given an array nums, there is a sliding window of size K which are moving from the very left of the array To the very right. You can only see the K numbers in the window. Each of the sliding window moves right by one position. Return the max sliding window.Example:Input:nums = [1,3,-1,-3,5,3,6,7], and k = 3Output: [3,3,5,5,6,7] Explanation:window position Max- -------------- ---
