Examples

use lib_rapid::compsci::stringhelpers::strcmp;
let a = "hello";
let b = "hEllo";
assert!(strcmp(a, b) == 101 - 69);
// 101 == 'e' in ASCII.
// 69 == `E` in ASCII.

use lib_rapid::compsci::stringhelpers::strcmp;
let a = "hello";
let b = "hello";
assert!(strcmp(a, b) == 0);

use lib_rapid::compsci::stringhelpers::strcmp;
let a = "Hello";
let b = "hello";
assert!(strcmp(a, b) == 72 - 104);
// 72 == 'H' in ASCII.
// 104 == `h` in ASCII.
