R(460个字符)
使用R的另一个版本。
从文件“输入”读取,输出到文件“输出”
d=as.list(as.integer(scan("input","",sep="\n")));n=36;f=rep(1,n);for(i in 3:n){f[i]=f[i-2]+f[i-1]};d2=lapply(d,function(x){a=vector("integer");i=1;while(x>0){id=which(f>=x)[1];if(x==f[id]){x=x-f[id];a[i]=f[id]}else{x=x-f[id-1];a[i]=f[id-1]}i=i+1}a});d=mapply(c,d,d2,SIMPLIFY=0);for(i in 1:length(d)){t=d[[i]];l=length(t);if(l==1){d[[i]]=paste(t[1],t[1],sep=": ")}else{d[[i]]=paste(t[1],": ",paste(t[2:l],collapse="+"),sep="")}}lapply(d,write,"output",append=1)

更具可读性的版本:

x <- x - fib[idx]
answ[i] <- fib[idx]
}
else {

answ[i] <- fib[idx-1]
}
i <- i + 1
}
answ})
dt <- mapply(FUN = c, dt, dt2, SIMPLIFY = FALSE)
