不使用算术运算运算符的十进制到二进制转换

在不使用算术运算运算符的情况下，找到给定非负数n的二进制等效项。
例子：

Input : n = 10
Output : 1010

Input : n = 38
Output : 100110

请注意，以下算法/程序中的+用于串联目的。
算法：

decToBin(n)
    if n == 0
        return "0"
    Declare bin = ""
    Declare ch
    while n > 0
        if (n & 1) == 0
            ch = '0'
        else
            ch = '1'
        bin = ch + bin
        n = n >> 1
    return bin
