已知 a1,a2,…a10a_1,a_2,…a_{10}a1,a2,…a10，满足 a1<a2,<…<a10a_1<a_2,<…<a_{10}a1<a2,<…<a10，且
∣a1∣+∣a2∣+…∣a10∣=256|a_1|+|a_2|+…|a_{10}|=256∣a1∣+∣a2∣+…∣a10∣=256
∣a1+1∣+∣a2+1∣+…∣a10+1∣=256|a_1+1|+|a_2+1|+…|a_{10}+1|=256∣a1+1∣+∣a2+1∣+…∣a10+1∣=256
∣a1+2∣+∣a2+2∣+…∣a10+2∣=256|a_1+2|+|a_2+2|+…|a_{10}+2|=256∣a1+2∣+∣a2+2∣+…∣a10+2∣=256
求 a5a_5a5 最大值
