Among the digits 123456789, pick and choose the sum close to 100, such as 89. Therefore I would attempt to get a value of 11 from 1234567 using different combinations. When you start working on a smaller sum now (sort of like divide and conquer), you may get the desired result.
What is the total if you add all the numbers from 1 to 100?
The sum of the numbers 1-100 would be equal to the number of pairs (50) multiplied by the sum of each pair (101), or 50 x 101 = 5,050.
How do you get the sum of all numbers from 1 to 100?
What is the total number from 1 to 100 in total?
so, → Total number of digits from 1 to 100 are = 9 + 90 * 2 + 3 = 9 + 180 + 3 = 192 digits (Ans.) therefore, the total number of digits from 1 to 100 are 192 .
How to arrive at 100 just using 1-9?
Our numbers 1 through 9 are. That’s almost half of 100 so we can multiply that by 2 and get 90 and now we can add back in another 1 and 9 to give the extra 10 needed to reach 100. So if we go back over what we have so far. Well, the way I did this is I first looked at how much adding the numbers 1 through nine would be.
How to make the answer 100 with numbers 1 to 9?
With numbers 1 to 9, we have to make the answer 100. How? You have numbers 1,2,3,4,5,6,7,8,9. You cannot change their sequence. You can only use + or -. You can also join two or three digits but only in order. eg: 12, 23, 34, 45, 56, 67, 78, 89 etc. You cannot use a number twice. Solve it. Who are the experts?
How to generate list of numbers from 1 to 100?
If you want your integers to be bound between two integers (i.e. start with something other than 1), you can use something like this: with bnd as (select 4 lo, 9 hi from dual) select (select lo from bnd) – 1 + level r from dual connect by level <= (select hi-lo from bnd);
How to select numbers from 1 to 100 in Oracle?
Using Oracle’s sub query factory clause: “WITH”, you can select numbers from 1 to 100: Peter’s answer is my favourite, too. If you are looking for more details there is a quite good overview, IMO, here. Especially interesting is to read the benchmarks.
