Given an integer array prices where prices[i] represents the stock price on day i, determine the maximum profit achievable. You may engage in multiple transactions (buy one and/or sell one share of the stock each day) but can hold at most one share at any time. Buying and selling on the same day is...
Exercise 2-1: Programming in C is fun! This task requires printing a specific string to the console. #include <stdio.h> int main() { printf("Programming in C is fun!"); return 0; } Exercise 2-3: Output Inverted Triangle Pattern Prints an inverted triangle pattern using asterisks and...
Understanding the Problem The objective is to verify if a given integer is a palindrome. A palindrome reads the same backward as forward. For integers, this means that if we reverse the sequence of digits, the value remains identical. The problem imposes a strict constraint: the solution must not us...
The Knuth-Morris-Pratt (KMP) algorithm reduces string matching complexity from quadratic O(N×M) to linear O(N+M) by eliminating redundant character comparisons. Instead of backtracking the text pointer upon a mismatch, the algorithm leverages precomputed structural information about the patern to sh...
Problem Set Overview This article presents solutions to five algorithmic problems from Meituan's 2024 Spring campus recruitment online assessment for software engineering positions. Each problem requires specific algorithmic techniques ranging from prefix sum optimization to union-find data structur...

Problem A: Rain Read four integers a, b, c, d and one target value x. For each of the four values, output 0 if it's greater than x, otherwise output x - value. #include <bits/stdc++.h> using namespace std; int main() { ios::sync_with_stdio(false); cin.tie(nullptr); int a, b, c, d, x; cin >&...
Problem A: Building Height Comparison Given an array of building heights, find the first building taller than the first one. #include <cstdio> const int MAX_SIZE = 105; int heights[MAX_SIZE]; int main() { int n; scanf("%d", &n); int result = -1; for (int i = 1; i <= n; i++) {...
To determine the number of operations required to reduce a non-negative integer to zero, specific rules apply based on parity. If the value is even, perform division by two. If the value is odd, subtract one. The process repeats until the value reaches zero. Consider the input 14. The sequence invol...
