Can you explain this example again? because i am geting different MD$5$ of "hello" and "world".

In this example, the MD$5$ hash values for "hello" and "world" are the same $("5$d$41402$abc$4$b$2$a$76$b$9719$d$911017$c$592"),$ indicating a collision. However, the SHA$-256$ hash values are different $("2$cf$24$dba$5$fb$0$a$30$e$26$e$83$b$2$ac$5$b$9$e$29$e$1$b$161$e$5$c$1$fa$7425$e$73043362938$b$9824"$ and $"7$c$211433$f$02071597741$e$6$ff$5$a$8$ea$34789$abbf$43$b$0$d$665$c$6$
