The same two pointer idea you mentioned is written on GFG (here) and it fails on the above case. Is there a way to do this in O(n) time and O(1) auxiliary space ? Reply | Complexity of the solution isO(N*log(N)) For every indexiwe'll try and find the smallest length subarray...
首先复制数组使用Arrays.copyOf() 将两次循环摘出来一个函数。 public int[] twoSumSix(int[] nums, int target) { int[] sortNums = Arrays.copyOf(nums, nums.length); Arrays.sort(sortNums); int i = 0; int j = sortNums.length - 1; while (i < j) { if (sortNums[i] + sortNums[j...
Given three integers n, k, and target, return the number of possible ways (out of the kn total ways) to roll the dice so the sum of the face-up numbers equals target. Since the answer may be too large, return it modulo 10^9 + 7. ...

Given two numbers represented as strings, return multiplication of the numbers as a string. Note: The numbers can be arbitrarily large and are non-negative. Converting the input string to integer is NOT allowed. You should NOT use internal library such as BigInteger. ...
[Leetcode 1, Medium] Two sum Problem: Given an array of integers, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2....
Try our best to make sure that the sum of numbers between each two cuts (inclusive) is large enough but still less than mid. We'll end up with two results: either we can divide the array into more than m subarrays or we cannot. ...
