Task 1: "Triplet Sum
You are given an array of real numbers greater than zero.
Write a script to find if there exists a triplet (a,b,c) such that 1 <
a+b+c < 2. Print 1 if you succeed otherwise 0.
Example 1:
Input: @R = (1.2, 0.4, 0.1, 2.5)
Output: 1 as 1 < 1.2 + 0.4 + 0.1 < 2
Example 2:
Input: @R = (0.2, 1.5, 0.9, 1.1)
Output: 0
Example 3:
Input: @R = (0.5, 1.1, 0.3, 0.7)
Output: 1 as 1 < 0.5 + 1.1 + 0.3 < 2
My notes: simple, I think it means "pick any 3 elements a, b and c from the
array and determine if any a,b,c triple sums to between 1 and 2", although both
successful examples show 3 ADJACENT elements a, b and c...
Task 2: "Power of Two Integers
You are given a positive integer $N.
Write a script to find if it can be expressed as a ** b where a > 0 and
b > 1. Print 1 if you succeed otherwise 0.
Example 1:
Input: 8
Output: 1 as 8 = 2 ** 3
Example 2:
Input: 15
Output: 0
Example 3:
Input: 125
Output: 1 as 125 = 5 ** 3
My notes: clearly defined, not quite sure how to do it so.. let's brute force
