\$\begingroup\$ Doing this in a lambda could make it shorter. \$\endgroup\$

\$\begingroup\$ @Okx It is recursive (so it would be longer), plus I don't do lambdas even if they would be shorter. \$\endgroup\$

\$\begingroup\$ The iterative version of your algorithm is way shorter as you remove the need to copy the array: boolean f(int[]c,int n){for(int l=c.length;l-->0;n-=n<c[l]?0:c[l]);return n<1;} (79 bytes). With Java 8 and its lambdas, it can further be reduced to 62 bytes. Regarding your answer as it currently is, int l=c.length-1 then using l instead of l-1 is also shorter. \$\endgroup\$
