首先建立一个累加的sum array 来记录每一个num 在nums 里的和(从0到num),便于在后面搜索的时候方便利用。 遍历中间的分割线 j 的范围(从左到右): 当分割线 j 确定了之后,分别遍历 分割线 i 和 k 在适当的范围内; 遍历分割线 i 的范围,从左边到j:找出 sum1(i左边)和 sum2(i右边)相等的所有情况,...
sum(i + 1, j - 1) = sum(2, 2) = 1 sum(j + 1, k - 1) = sum(4, 4) = 1 sum(k + 1, n - 1) = sum(6, 6) = 1 Note: 1 <= n <= 2000. Elements in the given array will be in range [-1,000,000, 1,000,000]. 给一个数组,找出三个位置,使得数组被分为四段,...

548. Split Array with Equal Sum i++ Given an array with n integers, you need to findifthere are triplets (i, j, k) which satisfies following conditions:1. 0 < i, i + 1 < j, j + 1 < k < n - 1 2. Sum of subarrays (0, i - 1), (i + 1, j - 1), (j + 1, k...
Test Input: n:3, a = 3 3 3 Output: 0 (we can't split the array so that they have equal sum) n:4, a = 2 2 2 2 Output: 2 (we can split the array into 2 2, 2 2 => then we can choose to continue with either left or right to 2, 2) ...
Finally, convertNto a numeric array and sum over it. N = str2double(N); sum(N) ans = 18 For a list of functions that create pattern objects, seepattern. Split String at Multiple Delimiters Create a string. str ="A horse! A horse! My kingdom for a horse!" ...
2578. Split With Minimum Sum Hint Given a positive integernum, split it into two non-negative integersnum1andnum2such that: The concatenation ofnum1andnum2is a permutation ofnum. In other words, the sum of the number of occurrences of each digit innum1andnum2is equal to the number of...
part_sizes(end+1) = N - sum(part_sizes); C = mat2cell(A, part_sizes, size(A,2)); C is now a cell array in which the rows are equally divided as possible, with the last block being shorter if necessary. 댓글 수: 2 ...
