Given a quantity n, discover the dice root of n.
Examples:Â
Â
Enter: n = 3
Output: Cubic Root is 1.442250
Enter: n = 8
Output: Cubic Root is 2.000000
Â
We will use binary search. First we outline error e. Allow us to say 0.0000001 in our case. The principle steps of our algorithm for calculating the cubic root of a quantity n are:Â
Â
- Initialize begin = 0 and finish = n
- Calculate mid = (begin + finish)/2
- Examine if absolutely the worth of (n – mid*mid*mid) Â
- If (mid*mid*mid)>n then set finish=mid
- If (mid*mid*mid)
Under is the implementation of above concept.Â

Python3
 Â
def diff(n, mid) :
    if (n > (mid * mid * mid)) :
        return (n - (mid * mid * mid))
    else :
        return ((mid * mid * mid) - n)
         Â
def cubicRoot(n) :
     Â
   Â
   Â
    begin = 0
    finish = n
     Â
   Â
    e = 0.0000001
    whereas (True) :
         Â
        mid = (begin + finish) / 2
        error = diff(n, mid)
 Â
       Â
       Â
       Â
        if (error <= e) :
            return mid
             Â
       Â
       Â
        if ((mid * mid * mid) > n) :
            finish = mid
             Â
       Â
       Â
        else :
            begin = mid
             Â
n = 3
print("Cubic root of", n, "is",Â
      spherical(cubicRoot(n),6))

Output:Â
Cubic root of three.000000 is 1.442250
Time Complexity: O(logn)
Auxiliary Area: O(1)
