Why Str_repeat,str_pad uses CHR to return ASCII code in a bit of a cryptographic algorithm in PHP

Why does Str_repeat,str_pad use CHR to return ASCII code in some cryptographic algorithms in PHP? Consider the following encryption algorithm: function Custom_hmac ($algo, $data, $key, $raw _output = False){$algo = Strtolower ($algo);$pack = ' H '. strlen ($algo (' Test '));$size = 64;$opad = Str_repeat (Chr (0x5C),

A good question about the minimal spanning tree! We need to construct a graph that contains only k vertices. However, if a brute-force graph is used, it will inevitably time out. Therefore, only the edges in the MST can be added, and the minimum spanning tree is obtained at the end. First of all, we can note that if each graph vertex is portal, the answer will be a sum of all edges 'weights in MST (minimal spanning tree ). we can find MST by using Kruskal's
