Python Challenges: Compute and return the square root of a given integer
Write a Python program to compute and return the square root of a given 'integer'.
Note: The returned value will be an ‘integer’.
Sample Solution:
Python Code:
def my_sqrt(x):
if x<2: return x
left=1
right=int(x/2)+1
while left<=right:
mid=int((left+right)/2)
if mid*mid==x:
return mid
if mid*mid>x:
right=mid-1
else:
left=mid+1
return right
print(my_sqrt(16))
Sample Output:
4
