Introduction Today, we will discuss DP, which stands for Dynamic Programming. There are many types of DP, such as Knapsack DP, Digit DP, Tree DP, and Bitmask DP… These are all advanced skills that I will share with you in the future. For today, let’s simply understand the basics of DP. 01 Dynamic Programming Concepts … Read more

📌 Problem Description Write a program to output the first n terms of the Fibonacci sequence (starting from 1, in the form of 1, 1, 2, 3, 5…). Requirements:1. Support input of any positive integer n2. Optimize time complexity to O(n)Example: Input: n=5 → Output: 1 1 2 3 5 Input: n=1 → Output: 1 … Read more
1. Mathematical Library Functions Content: Trigonometric functions (sin, cos, tan), logarithmic functions (log, log10), exponential functions (exp, pow). Key Points: Radian calculations, differences in precision between double and float. 2. Complex Dynamic Programming Content: Two-dimensional dynamic programming (grid paths), interval dynamic programming (stone merging), longest subsequence (LIS/LCS), rolling array optimization. Difficult Points: Derivation of state … Read more
