The Boolean OP1 AND OP2 operates bit-by-bit, setting a 1 in the result if the corresponding bit in OP1 and OP2 are both 1's. A similar operation is the Boolean OP1 OR OP2 which sets a 1 in the result of the corresponding bit in either OP1 or OP2 are both 1.
The number 5 is 101 in binary, while the number 4 is 100 in binary, so ANDing 5 and 4:
101
100
=
100
Since the "ones" bit is 1 in the number 5 and not in 4, it is zero in the result.
In Python the AND operator is "&", therefore in Python
a = 5 & 4
"a" will be 4.
This error message in Python programming indicates that you are trying to access an index that is outside the range of the array or list you are working with. In this case, you are trying to access index 4 in an array or list that only has a size of 4, causing the error.
-4 and 4
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5
0
no.. x equals 11
yes
No, it is not.
4 equals numbers in a current account pin number
x = 0
y=x+4
(x, y) = (3, 7) is a solution.
x=4 y=4
