#include <epu8.hpp>

Detailed Description

The first difference between two HPCombi::epu8.

Parameters

a,b	: two HPCombi::epu8
bound	: a size_t

Returns

the smallest index \(i<bound\) such that a[i] and b[i] differ, 16 if there is no differences before bound.

Example:

epu8 a { 5, 5, 2, 5, 1, 6,12, 4, 0, 3, 2,11,12,13,14,15};
epu8 b { 5, 5, 2, 9, 1, 6,12, 4, 0, 4, 4, 4,12,13,14,15};

then first_diff(a, b) returns 3, first_diff(a, b, 3) returns 16, first_diff(a, b, 4) returns 3, first_diff(a, b, 7) returns 3.

Warning

bound is assumed to be smaller or equal than 16
