// Implement a function that accepts 3 integer values a, b, c. The function should return true if a triangle can be built with the sides of given length and false in any other case.

// (In this case, all triangles must have surface greater than 0 to be accepted).

// Examples:

// Input -> Output
// 1,2,2 -> true
// 4,2,3 -> true
// 2,2,2 -> true
// 1,2,3 -> false
// -5,1,3 -> false
// 0,2,3 -> false
// 1,2,9 -> false
