题目描述
一只青蛙一次可以跳上1级台阶，也可以跳上2级。求该青蛙跳上一个n级的台阶总共有多少种跳法（先后次序不同算不同的结果）。
题目解析
这是一道经典的递推题目，你可以想如果青蛙当前在第n级台阶上，那它上一步是在哪里呢？
显然，由于它可以跳1级台阶或者2级台阶，所以它上一步必定在第n-1,或者第n-2级台阶，
也就是说它跳上n级台阶的跳法数是跳上n-1和跳上n-2级台阶的跳法数之和。

题目描述
将一个字符串转换成一个整数，要求不能使用字符串转换整数的库函数。
数值为0或者字符串不是一个合法的数值则返回0
输入描述:
输入一个字符串,包括数字字母符号,可以为空
输出描述:
如果是合法的数值表达则返回该数字，否则返回0
思路：1.先考虑第一个字符是否存在[+,-]
2.考虑字符串内是否有特殊字符，有就返回0
3.考虑字符串是否仅有[+,-]
4.考虑空字符串
