Problem Statement

Problem Description

You are given a real number x. Your task is to evaluate the following piecewise function f(x):

  • Case 1: If x < -1, then f(x) = x² - 3x + 2
  • Case 2: If -1 ≤ x ≤ 3, then f(x) = 2x + 5
  • Case 3: If x > 3, then f(x) = x³ - 10

Based on the value of x, determine which case applies and compute the corresponding function value.

Examples

  • For input -2, the output is 12.00 (Case 1)
  • For input 4, the output is 54.00 (Case 3)
  • For input 0, the output is 5.00 (Case 2)

Constraints

The input x satisfies: -1000 ≤ x ≤ 1000

Input Format

A single line containing one real number x.

Output Format

Output the computed value of f(x) formatted to exactly two decimal places.

Sample #1
Public sample
Input
-2
Output
12.00
Explanation
x = -2 falls in the first case (x < -1). f(-2) = (-2)² - 3(-2) + 2 = 4 + 6 + 2 = 12.00
Sample #2
Public sample
Input
4
Output
54.00
Explanation
x = 4 falls in the third case (x > 3). f(4) = 4³ - 10 = 64 - 10 = 54.00
Sample #3
Public sample
Input
0
Output
5.00
Explanation
x = 0, second case. f(0) = 2(0) + 5 = 5.00
