I can tell u the logic if the minimum existing coin denomination is 1 cent for instance.If the minimum denomination is not 1 u might need to modify the algorithm I guess
let v1,v2.....vn be the values of the coin denominations u have in the array dynamic programming solution would be as follows: we need another array to store all possible values using these coins that is say S[i] is the value i that is obtained using minimum number of coins so initialisation is S[0]=0; S[1]=1( if minimum denomination is 1 in given array) every other value S[i]= min( S[i-1] + 1, 1 if either of v1 to vn equals i) check and see if it is ok... arun On Fri, Jul 29, 2011 at 10:59 AM, AMAN AGARWAL <mnnit.a...@gmail.com> wrote: > what do u mean by > > memo[i]=memo[i-denom[j]] +1 > > memo[i] will be containing infinite value. > > memo[i-denom[j]] will also contain infinite value > > > > > On Fri, Jul 29, 2011 at 11:32 AM, ankit sambyal > <ankitsamb...@gmail.com>wrote: > >> Let S be the exact amount for which minimum coins are to found.
