Answer: (111000)2 = (70)8
Step by step solution:
Step 1: Write down the binary number
(111000)2
Group all the digits in sets of three starting from the LSB (far right). Add zeros to the left of the last digit if there aren't enough digits to make a set of three.
111 000
Step 2: Use the table below to convert each set of three into an octal digit. In this case,
111=7, 000=0.
So, the number 111000 in binary is equivalent to 70 in octal.
To convert from binary to octal use the following table:
Bin: 000 001 010 011 100 101 110 111
Octal: 0 1 2 3 4 5 6 7
Answer:
Following is the expression written in "Bash script" (mixture of commands):
^\d{5}(?:[-\s]\d{4})?$
Explanation:
- ^ = For staring string (denotation).
- \d{5} = Matching 5 digits (first five unknown x's)
- (?:…) = Making Group (making group of former 5 digits)
- [-\s] = Match a hyphen or a space
(checking if a hyphen is present?)
- \d{4} = Matching 4 digits (next four unknown x's)
- …? = Pattern before it is optional
- $ = Ending of the string.(denotation)
