you can't imagine what（）great difficulty we have had working out such （）difficult problem
这里两个空要填什么冠词，difficulty可数吗

difficulty是可数名词，所以我觉得第一个是difficulties然后前面不用加不定冠词
a difficult problem

第一个空不填，第二个填a。difficulty可数。

difficulty不可数，前一空填零冠词，即不填；problem是可数名次，后一空填不定冠词a限定problem。

a,a,difficulty可数.

the; a
