This repository contains the solutions and explanations to the algorithm problems on LeetCode. Only medium or above are included. All are written in C++/Python and implemented by myself. The problems attempted multiple times are labelled with hyperlinks. Topics algorithms leetcode cpp Resources Re...
4. Practice Recursion 4. 练习递归 Many linked list problems, like reversing in groups, can be elegantly solved using recursion.许多链表问题,例如分组反转,都可以使用递归来优雅地解决。 Understand how to convert recursive solutions to iterative ones and vice versa.了解如何将递归解决方案转换为迭代解决方...

Using Chebyshev's inequality, find an upper bound for having more than 120120 or less than 8080 customers in a day. That is, find an upper bound on P(X≤80 or X≥120).P(X≤80 or X≥120). Using the one-sided Chebyshev inequality (Problem 21), find an upper bound for having mor...
The merge sort algorithm divides the list into halves and merges them back together, resulting in a time complexity of O(n log n). Space Complexity: O(log n) for the recursive call stack. The merge sort algorithm uses recursion to sort the left and right halves, and the maximum depth ...

tree recursion (as for factorial vs. Fibonacci), and usage of one or more operators. These dimensions were identified from a psychological study of the difficulty of number series problems by Holzmann et al. [145]. Although IGOR2 is an AI system, the authors propose that IGOR2 can also ...
