Write a short note on the following in Microsoft Excel
1). MAX FUNCTION.
2). MIN FUNCTION.
3). AVERAGE FUNCTION.
4). INT FUNCTION
5). POWER FUNCTION
Answer:
Explanation:
1). The MAX function in Microsoft Excel is used to find the maximum value in a range of cells. For example, if you have a range of cells A1:A10 containing a set of numbers, you can use the formula "=MAX(A1:A10)" to find the maximum value in that range.
2). The MIN function in Microsoft Excel is used to find the minimum value in a range of cells. It works in a similar way to the MAX function, but returns the minimum value instead of the maximum value.
3). The AVERAGE function in Microsoft Excel is used to calculate the average of a set of values. It takes a range of cells as input and returns the mean of the values in that range.
4). The INT function in Microsoft Excel is used to round a number down to the nearest integer. It takes a number as input and returns the integer part of the number.
5). The POWER function in Microsoft Excel is used to calculate the value of a number raised to a certain power. It takes two arguments: the base number and the exponent. For example, the formula "=POWER(2,3)" returns 8, because 2 raised to the power of 3 is 8.

You want to know which files are large files (at least 0.1MB) in your data directory, but you do not want to go through them one by one. So you decide to design a regular expression to help with this. Locate the rule under the p1 target in your Makefile. This rule uses the Is command to list the contents of the data directory in your current folder. The -I option produces the long listing for these contents, which includes their size in bytes. The output of this is command is then piped as input into grep command. The-E option for the grep command allows searching through this text with a regular expression. Replace the regular expression in this grep command to search for any 6 digit number. Since the size of these files are displayed in bytes, the smallest possible six digit number: 100000 corresponds to 0.1MB. When this regular expression is correct, running "make p1" should display the three large files that can be found within the provided data directory. Tip: Start by composing a regex that matches any single digit, and test this to make sure that it works as expected. If you encounter trouble with one specific way of matching single digits, like \d, then please try to find another way that works with grep - E. Once this is working, look for a way to extend this pattern so that it must be repeated exactly six times to be matched.
You must pipe the command's output through grep in order to utilize grep as a filter. " | " is the symbol for pipe.
Explain about the grep?The full line containing the matched string is displayed by default when using grep. To display only the matched pattern, change this setting. Using the -o option, we may instruct grep to show only the matching string. Using grep -n, output should be displayed together with the line number: To display the file's line number where the matching line was found.
Within collections of files, the grep command can look for a string. It outputs the name of the file, a colon, the line that matches the pattern, and the pattern when it discovers a pattern that matches in more than one file.
Instead of putting a filename at the end of a grep command, use an asterisk to search all files in the current directory.
