puts mystr
数组
废话少说，直接上代码。
## 1、数组定义
arr1 = []
arr2 = Array.new
arr3 = ['1','2','3']
## 2、输出
puts "Output:n"
print arr3,"n" # 输出：["1", "2", "3"]
puts arr3[0] # 输出：1
print arr3.join(",") # 输出：1,2,3
## 3、访问数组元素
puts "nArray Elementn"
puts "n", arr3[0]
puts "n", arr3[-1] #这个比较有意思，意思是最后一个的数据
puts "n", arr3.first
puts "n", arr3.last
puts "n", arr3.max
puts "n", arr3.min
puts "n", arr3.length
puts "n", arr3.size
## 4、数组操作
puts "nArray methodn"
puts "n", arr3[4] = '5' #此时arr3[3]默认尾nil
puts "n", arr3.delete_at(3) #删除指定下标的元素
puts "n", arr3[2] = ["3a","3b","3c"] #可以这样来做
puts "n", arr3.delete(["3a","3b","3c"]) #可以删除上面添加的
puts "n", arr3.push('6') #插入元素
puts "n", arr3.insert(3,"b") #在指定位置插入新元素
puts "n", arr3<<"f"<<2 #从左至右一次加入元素
puts "n", arr3.pop #删除尾元素
puts "n", arr3.shift #删除首元素
puts "n", arr3.clear #清空数组
## 5、数组运算
puts "nArray Operatorn"
aaa = [" aa ",4,5," bb "]
bbb = [4,1,3,2,5]
print aaa + bbb,"n" # 输出：[" aa ", 4, 5, " bb ", 4, 1, 3, 2, 5]
print aaa*2,"n" # 输出：[" aa ", 4, 5, " bb ", " aa ", 4, 5, " bb "]
print bbb - aaa,"n" # 输出：[1, 3, 2]
print aaa | bbb,"n" # 输出：[" aa ", 4, 5, " bb ", 1, 3, 2]
