Explanation: The concatenation results in "1101110010111011110001001101010111100". The decimal value of that is 118505380540. After modulo 109 + 7, the result is 505379714. Constraints: 1 <= n <= 105 解题思路:直接计算吧,能AC。 代码如下:
binary sequences can represent a wide variety of information, from simple values like numbers and strings to complex data such as images, audio files, and executable code. each bit (0 or 1) in a binary sequence represents either one or zero, which translates into the traditional data types ...
What is the purpose of BCD adders? BCD adders are digital circuits used to perform arithmetic operations on BCD-encoded numbers. BCD adders can add or subtract two BCD numbers and produce a result in BCD format. How does BCD differ from gray code in terms of bit patterns?

You are given two huge binary integer numbers aa and bb of lengths nn and mmrespectively. You will repeat the following process: if b>0b>0, then add to the answer the value a & ba & b and divide bb by 22 rounding down (i.e. remove the last digit of bb), and repeat the proce...
In this code, each digit individually is encoded in straight binary. For example, the number 149 encoded in BCD would be 0001 0100 1001 (a binary 1, a binary 4, a binary 9). The advantage of BCD is that each binary number has to be only 4 bits in order to span the range 0–9...
