[teng125]

Consider the square root operation. Suppose an integer numbers i > 0 as input variable.
Design an algorithm which calculates the greatest natural number less than or equal to
the square root of the input variable i.


can smby pls explain to me what does this ques mean??if possible explain using some example

thanx

A natural number just means a positive integer, like 1, 2, 3, 4, 5.

Here are some examples of what your algorithm should do:
sqrt(1) = 1
sqrt(2) = 1
sqrt(3) = 1
sqrt(4) = 2
sqrt(5) = 2
sqrt(57) = 7
sqrt(170) = 13
