How to find a triplet that sum to a given value?

Loop over the array and fix the first element of the possible triplet, arr [i]. Then fix two pointers, one at i + 1 and the other at n – 1. And look at the sum, If the sum is smaller than the required sum, increment the first pointer. Else, If the sum is bigger, Decrease the end pointer to reduce the sum.

How to calculate sum of digits from 1 to 299?

For 328, sum of digits in numbers from 1 to 299. For 328, we compute 3*sum (99) + (1 + 2)*100. Note that sum of sum (299) is sum (99) + sum of digits from 100 to 199 + sum of digits from 200 to 299. Sum of 100 to 199 is sum (99) + 1*100 and sum of 299 is sum (99) + 2*100.

What are three consecutive integers have a sum of 21?

Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math: Which means that the first number is 6, the second number is 6 + 1 and the third number is 6 + 2. Therefore, three consecutive integers that add up to 21 are 6, 7, and 8.
