Jumps One of the signal features of Scheme is its support for jumps or nonlocal control. Specifically, Scheme allows program control to jump to arbitrary locations in the program, in contrast to the more restrained forms of program control flow allow…
A procedure body can contain calls to other procedures, not least itself: (define factorial (lambda (n) (if (= n 0) 1 (* n (factorial (- n 1)))))) This recursive procedure calculates the factorial of a number. If the number is 0, the answer is 1. For…
题目: Given an array of non-negative integers, you are initially positioned at the first index of the array. Each element in the array represents your maximum jump length at that position. Your goal is to reach the last index in the minimum number of j…

Drracket continuation 文中使用let/cc代替call/cc Racket文档中,let/cc说明为: (let/cc k body ...+) Equivalent to (call/cc (lambda (k) body ...)). 首先,通过一个简单的函数来测试下continuation,注意,下面的函数执行会导致无限循环 #lang racket (define r #f) (define (f) (let/cc k ;开始捕获continuation,从let/…

URL Scheme 的作用 客户端应用可以向操作系统注册一个 URL Scheme,该 Scheme 用于从浏览器或其他应用中启动本应用. 通过指定的 URL 字段,可以让应用在被调起后直接打开某些特定页面,比如:书籍封面页,书城页面,原创页面,订单详情页.充值页,促销广告页等等.也可以执行某些指定动作,如订单支付等.也可以在应用内或者应用外,通过 html 页来直接调用显示 app 内的某个页面. URL Scheme 的格式 客户端自定义的 URL 作为从一个应用调用另一个的基础,遵循 R…
前言: 最近公司业务发展迅速,单一的项目工程不再适合公司发展需要,所以开始推进公司APP业务组件化,很荣幸自己能够牵头做这件事,经过研究实现组件化的通信方案通过URL Scheme,所以想着现在还是在预研阶段,很有必要先了解一下URL Scheme,看看是如何使用的?其实在之前做Hybrid混合编程的时候就接触过URL Scheme,总来的来说还不算陌生,今天就来回顾总结一下.业务组件化相关博客地址(Android业务组件化之现状分析与探讨) 业务组件化相关文章地址: Android业务组件化之…
