Hướng dẫn get least significant bit python - nhận được ít trăn bit quan trọng nhất

"Byte" của bạn có phải là int không? Nếu vậy, chỉ cần dùng bitwise và (&) với 1 (hoặc, nếu bạn muốn rõ ràng hơn, nghĩa đen nhị phân 0b1) để có được bit ít đáng kể nhất.

>>> x = 14
>>> x & 1
0
>>> x = 15
>>> x & 1
1

Là đối tượng "byte" của bạn là một đối tượng bytes? Nếu vậy, chỉ cần lập chỉ mục vào nó và lấy bitwise và.

>>> y = bytes([14, 15])
>>> y[0] & 1
0
>>> y[1] & 1
1

    Input : num = 10, k = 4 
    Output : 1
    Explanation : Binary Representation 
    of 10 is 1010. 4th LSB is 1.
    
    Input : num = 16, k = 3
    Output : 0
    Explanation : Binary Representation 
    of 16 is 10000. 3rd LSB is 0.

    1. Một số N được đưa ra. Chúng ta cần in ‘K Khănth Bit.examples ít quan trọng nhất của nó: & nbsp; & nbsp;
    2. Chúng ta có thể dễ dàng giải quyết vấn đề này bằng các bước sau: & nbsp;
    3. Thay đổi số ’1 1 (K-1) lần còn lại.

    C++

    #include <bits/stdc++.h>

    Điều này sẽ mang lại một số với tất cả các bit không được đặt nhưng bit ‘k hèth. Bây giờ, chúng tôi sẽ thực hiện logic và số đã thay đổi với số đã cho.

    Tất cả các bit ngoại trừ bit ‘k hèth sẽ mang lại 0 và bit’ K K sẽ phụ thuộc vào số. Điều này là do, 1 và 1 là 1. 0 và 1 là 0.

    Làm thế nào để bạn có được một chút đáng kể nhất trong Python?

    Nếu vậy, chỉ cần dùng bitwise và (&) với 1 (hoặc, nếu bạn muốn rõ ràng hơn, 0b1 theo nghĩa đen) để có được bit ít đáng kể nhất.take bitwise AND ( & ) with 1 (or, if you want to be more explicit, the binary literal 0b1 ) to get the least significant bit.

    Làm thế nào để bạn tìm thấy bit ít quan trọng nhất?

    Để chắc chắn rằng bạn có được bit/giá trị phù hợp: giá trị ở vị trí bit ít nhất có ý nghĩa nhất = x & 1. Giá trị của số ít có ý nghĩa nhất 1 = x & -x.Chỉ số dựa trên không có ý nghĩa nhất được cô lập 1 = log2 (x & -x)The value at the least significant bit position = x & 1. The value of the isolated least significant 1 = x & -x. The zero-based index of the isolated least significant 1 = log2(x & -x)

    Là bit 0 lsb hay msb?

    Trong một số nhị phân, bit xa nhất bên trái được gọi là bit quan trọng nhất (MSB) và bit xa nhất bên phải được gọi là bit ít có ý nghĩa nhất (LSB).MSB đưa ra dấu hiệu của số (bit dấu hiệu), 0 cho dương và 1 cho âm.Các bit còn lại giữ độ lớn của số.0 for positive and 1 for negative. The remaining bits hold the magnitude of the number.

    Ý nghĩa của LSB là gì?

    Bit ít quan trọng nhất.Trong một số nhị phân, LSB là bit có trọng số ít nhất trong số.Thông thường, các số nhị phân được viết bằng MSB ở vị trí nhất bên trái;LSB là bit xa nhất.. In a binary number, the LSB is the least weighted bit in the number. Typically, binary numbers are written with the MSB in the left-most position; the LSB is the furthest-right bit.
