1. Title:Returns the and of the largest sub-array in an integer array.2. Requirements:Enter an array of shapes with positive and negative numbers in the array.One or more consecutive integers in an array make up a sub-array, each of which has a and.If the array a[0] ... A[j-1] next to each other, allowing a[i-1], ... A[n-1], a[0] ... A[J-1] and the largest.Returns the position of the largest subarray at the same time.The maximum value for the and of all sub-arrays. Requires a time complexity of
How can I Traverse tables without consecutive fields updated? A mysql table has the following field IDs. cs and id are the primary key, but the values are not consecutive ,..... in this case, I need to traverse the update table and write the code. the following query does not know how to loop through PHPcode. how can I traverse the update table without consecutive fields?
A mysql table with the following fields
Id, cs,
The id is a primary key, but the value is not consecutive.
1, 3, 7, 8, 9, 10
Tree array templates
Tree arrays are much more efficient in the process of adding single points and summing up intervals than in the line tree. Therefore, it is necessary to learn (personal opinion)
Lowbit: I (-I)
You can use add directly for single-point addition. If there are other operations, you can write another function.
For the sum, you can directly use summax minus the summin-1 to obtain the range and ratio, the Code complexity is much lower
Pair member : Hou Tao Bright: mainly responsible for programming code.Zhu Shaohui: Mainly responsible for program debugging and modification.title: A two-dimensional array of the end-to-end, in which there is a positive number, a negative number, to find its maximum sub-matrix.idea: The solution of this problem is to find the maximal sub-matrix of the two-dimensional array and the largest sub-array and combine with the first dimension. The maximum number of sub-arrays for the solution ring can b
Today, we begin to brush the title on 51nod. As a novice in this problem on the pit ... You should pay attention to the data type and look at the library function more after doing the problem. For example, the ABS () return type is int.#include #include#defineINF 100000;intMain () {intN; Long Longmin=inf; Long Longsum=0; Long LongT; scanf ("%d",N); while(n--) {scanf ("%lld",t); Sum+=T; if(summin) min=sum; } if(min0) printf ("%lld\n",-min); Elsep

-1], if it is the largest sub-array must have SUN+A[J]>A[J] that is sum>0, otherwise a[j] assigned to sum. The second case is when the array is out of bounds, such as 1 3 2 -9-4 6this is equivalent to solving the smallest subarray in the array (as with the maximum subarray principle), and then using the entire array and subtracting the youngest array, the maximum subarray is obtained. Three codes#include using namespacestd;intMAX (intS[],intN) { inti,sum=0, max=s[0]; for(i=0; i) {
