The diff function in numpy can find the difference between each of the numbers after they are sorted. numbers = [1,1,2,4,5,3,2,1,6,3,1,6] count_sixes = numbers.count (6) Super simple. Now to my question, is this a good approach or should I choose another, as … Java program to calculate the sum of N numbers using arrays, recursion, static method, using while loop. One important fact is we can not find consecutive numbers above N/2 that adds up to N, because N/2 + (N/2 + 1) would be more than N. So we start from start = 1 till end = N/2 and check for every consecutive sequence whether it adds up to N or not. We can use that solution and find the required count using below steps. For example, it always returns true if there's zero or one number passed. 312. posted 5 years ago.
