optimization. Add an array to overwrite O (NV. The idea is to add an array CNT [], CNT [J] to indicate the number of I coins used when the nominal value is J. So (0 Then I changed it a bit. Let the initial value of CNT [] Be C [I], and then CNT [J] = CNT [J-A [I]-1 each time the transfer condition is met; here CNT [J] indicates the number of coins in I after several I
