MIn coin change top down approach

this testcase is not giving the correct ans .
18 // value
3 // no of coins
6 8 10 // value of coins
My code link is


  • Line 10: int ans = INT_MAX;
    Consider this function call -> F(18) -> F(8) -> F(2):
    Now F(2) will return INT_MAX, and in the parent call F(8): Line 14:

    ans = min(ans,subprob+1);

subprob is INT_MAX, thus suburb+1 = INT_MIN, which would eventually yield itself as answer.

Try this instead:

  • Line 10: int ans = INT_MAX-1;
