- There is only one duplicate number in the array, but it could be repeated more than once. 代码如下: public int findDuplicate(int[] nums) { if (nums.length > 1){ int slow = nums[0]; int fast = nums[nums[0]]; //以下为求两个指针第一次相遇的点 while (slow != fast){ slow...
Find the Duplicate Number Given an array nums containing n + 1 integers where each integer is between 1 and n (inclusive), prove that at least one duplicate number must exist. Assume that there is only one duplicate number, find the duplicate one. Note: You must not modify the array (as...

In this Java tutorial, we discussed the two approches to find all duplicate words in aStringand how many number of times they apprear in that String. These Java programs can be used to find the unique words in a string too. Happy Learning !!
Java programming exercises and solution: Write a Java program to find the median of the numbers inside the window (size k) at each step in a given array of integers with duplicate numbers. Move the window to the array start.
