Given a list, print the number of numbers in the given range. Show Examples: Input : [10, 20, 30, 40, 50, 40, 40, 60, 70] range: 40-80 Output : 6 Input : [10, 20, 30, 40, 50, 40, 40, 60, 70] range: 10-40 Output : 4 Multiple Line Approach: Python
Single Line Approach: x for x in list1 if l <= x <= r The return value(true) of the
condition check is stored in a list, and at the end the length of the list returns the answer. Python
Approach#3 : Using sum We can use sum in this problem. We use list comprehension to iterate over the list and check number is in range or not if it is present comparison will have 1 as have else 0 as value. Sum function return the sum of total of parameters. Python3
Using the built-in function filter():This function takes a function and an iterable as arguments and returns a new iterable containing only the elements for which the function returns True. To count the number of numbers in the given range, we can define a lambda function that checks if a number is in the range, and then pass this function to filter() along with the list. The length of the resulting iterable will be the number of numbers in the range. Here is an example of how to use this approach: Python3
This will output 6, as in the other solutions. The time complexity of this approach is O(n), where n is the length of the list, and the space complexity is O(n), since filter() creates a new iterable containing all the elements that satisfy the condition. What function determines how many numbers are in a range?Use the COUNT function to get the number of entries in a number field that is in a range or array of numbers. For example, you can enter the following formula to count the numbers in the range A1:A20: =COUNT(A1:A20).
Which function is used to total a range of cells?You can use a simple formula to sum numbers in a range (a group of cells), but the SUM function is easier to use when you're working with more than a few numbers. For example =SUM(A2:A6) is less likely to have typing errors than =A2+A3+A4+A5+A6.
What function used to count the cells with a specified content within a range?The COUNTIF Function[1] will count the number of cells that meet a specific criterion.
What function is used to find the total number?The SUM Function. The SUM function is used when you need to calculate totals for a range of cells or a group of selected cells on a worksheet.
