Ivan is fond of collecting. Unlike other people who collect post stamps, coins or other material stuff, he collects software bugs. When Ivan gets a new program, he classifies all possible bugs into n categories. Each day he discovers exactly one bug…
def MaxSum(self,array,n): sum=array[0] result=array[0] for i in range(0,n): if sum<0: sum=a[i] else: sum=sum+a[i] start1=i if sum>result: result=sum end=i start=start1 print result,start,end 上述采用的是动态规划思想:假设sum[i]表示以第i个元素结尾的最大连续字串,那么sum[i]=max{sum[i-…
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. 递归方程; dp[i] = dp[i-1]+nums[i]…
