How many numbers less than 904 are divisible by 3

The problem is to find for each element in the array nums , how many elements are smaller than the current element. In other words, you walk through each item in the input list, and for each of these items, you need to count all other numbers in the list that are less than it. It's important to remember that you should not include the current element in the count. The goal is to create an output array of the same length as nums where each index contains this count of smaller numbers. Here, four numbers are smaller than 8, no number is smaller than 1, one number is smaller than the first occurrence of 2, and so on. Sorting : We could sort the array and then map each element to its corresponding index, but this would lose the original order of the elements, which we need to preserve. Counting Sort Principle: Since we know the elements in nums are integers and the problem typically has constraints that limit their range not stated in the problem description here but usually up to , we can use a counting sort approach. This means we tally how many times each number occurs the frequency , and then we can deduce how many numbers are smaller by looking at numbers frequencies to the left of the current number. The intuition behind the provided solution is to build a frequency array cnt with an extra element so we can easily accumulate the counts. We use the accumulate function from Python's itertools to get a prefix sum of counts, effectively giving us a running total of how many numbers are smaller than each value up to assuming nums contains numbers up to for this argument. By doing this, s[x] corresponds to the count of numbers less than x in the original array, as desired. Thus, s is used to create the output result conveniently and efficiently.

We will start off with a couple of definitions for clarification. Three digit numbers 3-digit numbers are numbers that have three digits in them. They range from to Therefore, there are a total of 3-digit numbers. Furthermore, a three digit number is divisible by if you divide the three digit number by and you get a whole number with no remainder. Below you will find many questions and answers related to three digit numbers divisible by

The divisibility rule of 3 states that if the sum of the digits of a whole number is a multiple of 3, then the original number is also divisible by 3. With the help of the multiplication table of 3 or by using skip counting by 3 starting at 0 and adding 3 it is easy to find whether a smaller number is divisible by 3 or not. However, for larger numbers, we can check if that number is completely divisible by 3 or not without doing the actual division. A whole number is said to be divisible by 3 if the sum of all digits of that whole number is a multiple of 3 or exactly divisible by 3. The divisibility rule for 3 can be understood with the help of the following examples. Since 18 is divisible by 3, it means is also divisible by 3. Since 6 is divisible by 3, it means is also divisible by 3. Since 17 is not divisible by 3, it means is not exactly divisible by 3.

How many numbers less than 904 are divisible by 3

If a number is divisible by 3 it means that the number is in the 3 times table. Firstly, add the individual digits of a number. Then check to see if this answer is in the 3 times table.
