Angle_Between_Time.cpp

// A wall clock is a complete whole circle and cover 360°.
// You are given the time as HH:MM.
// Your task is to return the angle between the Hours hand and Minutes hand
// of the clock and the angle should not be reflex angle.

// Input Format:
// -------------
// A string time, HH:MM

// Output Format:
// --------------
// Print a double result, within 10^-5 of the original value.


// Sample Input-1:
// ---------------
// 04:30

// Sample Output-1:
// ----------------
// 45.00000


// Sample Input-2:
// ---------------
// 06:15

// Sample Output-2:
// ----------------
// 97.50000
