Input: head = [1], pos = -1 Output: no cycle Explanation: There is no cycle in the linked list. Follow up: Can you solve it without using extra space? 【Find the Duplicate Number】Given an arraynumscontainingn+ 1 integers where each integer is between 1 andn(inclusive), prove that...

The question in the title (and the last line) seems to have little to do with the actual body of the question. If you're trying to find amicable pairs, or computing the sum of divisors for many numbers, then separately factorising each number (even with the fastest possible algorithm) is...
Yang and Zhang20, introduced an algorithm based on the common neighbors and distance metric to predict link in a variety of real world networks from the available topological structure of the network. The algorithm aims to find missing link probability between nodes who do not have common ...
I am looking for a fast, integer only algorithm to find the square root (integer part thereof) of an unsigned integer. The code must have excellent performance on ARM Thumb 2 processors. It could be assembly language or C code. Any hints welcome....
