RSS订阅原创 TS vs JS
TypeScript 最大的优势就是通过静态类型将运行时错误转化为编译时错误，这带来了：更早发现错误 - 在编码阶段而非用户使用时更好的开发体验 - 智能提示、自动补全更高的代码质量 - 明确的接口契约更强的可维护性 - 安全的重构和修改这正是为什么 TypeScript 在现代前端开发中如此受欢迎的原因！🎯。

原创 Photoshop混合模式
文章摘要： 本文系统介绍了Photoshop混合模式的分类及特性，将28种模式分为基础型、变暗型、变亮型、对比型、比较型和色彩型6大类。基础型如"正常"和"溶解"实现基本覆盖效果；变暗型（如"正片叠底"）通过算法保留暗部；变亮型（如"滤色"）则突出亮部；对比型（如"叠加"）增强图像层次；比较型（如"差值"）产生反相效果；色彩型（如"色相"）控制特定色彩属性。每种模式均标

原创 Typescript return type
简单来说，记住这三条规律：字符串：所有方法都安全无副作用，返回新字符串。数组：方法名听起来像“动作”的（如pushsort）通常会修改原数组；方法名听起来像“查询”或“创建”的（如mapslice）通常返回新数组。Mapsetdeleteclear会修改原 Map，其他查询方法则不会。

原创 编程竞赛中的“魔法数字”：为什么总是对 10^9+7 取模？
编程竞赛中常见的模数10^9+7并非随意选择，而是基于数学与工程考量的黄金标准。作为大素数，它支持模逆元运算，满足组合数学和数论定理的需求；其数值大小(约2^30)完美适配32/64位整数计算，避免溢出风险。变体如合数10^9+5常被用作"陷阱"，考察选手是否真正理解模运算原理。特殊素数998244353则适用于需要数论变换的题目。这一设计完美平衡了数学严谨性、计算效率与出题意图，是计算机科学实践智慧的结晶。

原创 编程竞赛中的“魔法数字”：为什么总是对 10^9+7 取模？
编程竞赛中常见的模数10^9+7是精心设计的黄金标准：作为大素数，它支持模逆元运算，满足组合数学等计算需求；其数值大小恰好匹配32/64位整数的存储范围，避免溢出；变体如10^9+5可能提示解法无需逆元，998244353则适用于数论变换。这个数字完美结合了数学严谨性与工程实用性，是算法竞赛中的重要工具。

原创 贪心和DP的区别是什么？
贪心算法可以看作DP在“局部最优性恒成立”时的特例，但大多数情况下，贪心策略无法保证全局最优（如非贪心选择性问题）。贪心是“短视但高效”的单向选择，DP是“全面但复杂”的系统穷举。：DP会系统地遍历所有可能的子问题（如通过状态转移方程），而贪心只选“当前最优”。：DP的状态转移可能依赖多个前驱状态（如背包问题），而贪心的选择是单向的。：贪心确实是局部最优推进，DP确实依赖子问题解（DAC+记忆化）。：通过递归分解问题，记录子问题的解（记忆化），避免重复计算。：DP能解决的问题更广泛，尤其是当问题需要。
