### Test Suite

Test Status Code Input and Output
1   Pass
%% x = pi; y_correct = '3 + 1/(7 + 1/(16))'; assert(isequal(contfractions(x),y_correct))

``` ans = 3 + 1/(7 + 1/(16)) ```

2   Pass
%% x = exp(1); y_correct = '3 + 1/(-4 + 1/(2 + 1/(5 + 1/(-2 + 1/(-7)))))'; assert(isequal(contfractions(x),y_correct))

``` ans = 3 + 1/(-4 + 1/(2 + 1/(5 + 1/(-2 + 1/(-7))))) ```

3   Pass
%% x = sqrt(2); y_correct = '1 + 1/(2 + 1/(2 + 1/(2 + 1/(2 + 1/(2 + 1/(2 + 1/(2 + 1/(2))))))))'; assert(isequal(contfractions(x),y_correct))

``` ans = 1 + 1/(2 + 1/(2 + 1/(2 + 1/(2 + 1/(2 + 1/(2 + 1/(2 + 1/(2)))))))) ```

4   Pass
%% x = (exp(1)-1)^-1; y_correct = '1 + 1/(-2 + 1/(-3 + 1/(2 + 1/(5 + 1/(-2 + 1/(-7 + 1/(2)))))))'; assert(isequal(contfractions(x),y_correct))

``` ans = 1 + 1/(-2 + 1/(-3 + 1/(2 + 1/(5 + 1/(-2 + 1/(-7 + 1/(2))))))) ```

5   Pass
%% filetext = fileread('contfractions.m'); assert(isempty(strfind(filetext, 'switch'))) assert(isempty(strfind(filetext, 'case')))
