Triplets with Sum between given range Interviewbit Solution

Problem Description:

Given an array of real numbers greater than zero in form of strings. Find if there exists a triplet (a,b,c) such that 1 < a+b+c < 2 . Return 1 for true or 0 for false.


Given [0.6, 0.7, 0.8, 1.2, 0.4] ,
You should return 1
Hence, the output is 1.
O(n) solution is expected.

Note: You can assume the numbers in strings don’t overflow the primitive data type and there are no leading zeroes in numbers. Extra memory usage is allowed.
