The square root of a number $$N$$ is to be obtained by applying the Newton $$-$$ Raphson iteration to the equation $$\,{x^2} - N = 0.\,\,$$ If $$i$$ denotes the iteration index, the correct iterative scheme will be
A
$${x_{i + 1}} = {1 \over 2}\left[ {{x_i} + {N \over {{x_i}}}} \right]$$
B
$${x_{i + 1}} = {1 \over 2}\left[ {x_i^2 - {N \over {x_i^2}}} \right]$$
C
$${x_{i + 1}} = {1 \over 2}\left[ {{x_i} + {{{N^2}} \over {{x_i}}}} \right]$$
D
$${x_{i + 1}} = {1 \over 2}\left[ {{x_i} - {N \over {{x_i}}}} \right]$$
