内容简介:Find the contiguous subarray within an array (containing at least one number) which has the largest sum.For example, given the array [−2,1,−3,4,−1,2,1,−5,4],the contiguous subarray [4,−1,2,1] has the largest sum = 6.
Find the contiguous subarray within an array (containing at least one number) which has the largest sum.
For example, given the array [−2,1,−3,4,−1,2,1,−5,4],
the contiguous subarray [4,−1,2,1] has the largest sum = 6.

More practice:
If you have figured out the O(n) solution, try coding another solution using the divide and conquer approach, which is more subtle.
func maxSubArray(_ nums: [Int]) -> Int { if nums.isEmpty { return 0 } var gMax = nums[0], lMax = nums[0] for i in 1..<nums.count { lMax = nums[i] + max(lMax, 0) gMax = max(gMax, lMax) } return gMax }(随着网站访问量的激增,服务器配置只得一再升级以维持网站不“404 Not Found”,所以网站的维护费用也在不断上涨……(目前的阿里云服务器ECS+云数据库RDS+域名购买+七牛云的费用是2200元/年),为了能不放弃该网站,所以我又把打赏链接放上来啦~所有打赏金额都会被记账并投入博客维护中,感谢厚爱,多多关照~)
