### Flow chart

- ### Euclide GCD
-- Mermaid code：

graph TD
    .((start)) --> A(input a, b)
    A --> |loop| B[c = a mod b]
    B --> C{c = 0 ?}
    C -->|yes| D(print b)
    D --> ..((stop))
    C -->|no|E[a = b, b = c]
    E --> C

graph TD
	.((start)) --> A(input a, b)
	A --> |loop| B[c = a mod b]
	B --> C{c = 0 ?}
	C -->|yes| D(print b)
	D --> ..((stop))

- ### Quadratic Equation
-- Mermaid code：

graph TD
    .((start)) --> A(input a, b, c)
    A --> B[del = b^2 - 4ac]
    B --> C{del >= 0 ?}
    C --> |yes| D["x1 = (-b + sqrt(del))/(2a)"]
    D --> F["x2 = (-b - sqrt(del))/(2a)"]
    F --> H(print x1, x2)
    H --> M((stop))
    C --> |no| E(print 'No real solution')
    E --> M
