Change the following line in InsertSymbol() function temp =temp.Insert(loc[j] -1  token[j].ToString()); to temp =temp.Insert(loc[j] token[j].ToString()); It was another problem i left with

Hi Amit Thanks for your code.... it looks really cool but I think that somewhere there is a small bug :( Consider the following inputs: string s1 = bottom; string s2 = **1*2*; The answer I am getting for your code is the following: b2112m bo22om bo11om but it should be as follows: bo1tom bott2m bo1t2m what do you think?

hi sa... input string: botle Substitute string: **1*2 use trim function for input string and substitute string... like s1=s1.Trim(); and s2=s2.Trim() it'll remove all the leading and trailing spaces if comes by accident. I think the last post was working for you. Cheers coding

hi again I changes to the following part of the code: temp = source; for (int j = 0; j { string token = Tokens[i]; if (sourceSubst.IndexOf(token[j]) == loc[j]) { temp = temp.Remove(loc[j] 1); temp = temp.Insert(loc[j] token[j].ToString()); } else { temp = temp.Remove(sourceSubst.IndexOf(token[j]) 1); temp = temp.Insert(sourceSubst.IndexOf(token[j]) token[j].ToString()); } } and it seems to be working fine.... can you please confirm please??

Thanks again since you used 'AxxoSt' as a testing string you did not captured the following error: When I tried with the following I got the following result: input string: botle Substitute string: **1*2 ============Output============ bo1l2 -> correct bole2 -> should be botl2 bo1le -> correct

Sa Za · Answer

Thanks I am seeing the code and the problem is in the following part: for (int j = 0; j { string token = Tokens[i]; //get char to change temp = temp.Remove(loc[j] 1);//remove it from orig string temp = temp.Insert(loc[j] token[j].ToString()); //replace it with the new char } because when you are replacing one character it is always taking the first position. Note that s2 can have identical characters at different possitions (eg: **a*ac)

Sa Za · Answer

Hi Amit I did not understood your last post maybe I was not clear :) When I run the program after the fixes you gave me the results are not good. The code should give the following results: but they should be as: bo1tom bott2m bo1t2m but you gave me the following: bo1t2m -> correct bo2tom -> '2' should be placed instead of the 'o' bo1tom -> correct thanks again

Hi Amit Thanks for your help .. it is really appreciated. But there is still a problem: The results I am getting now are the following: bo1t2m bo2tom bo1tom but they should be as: bo1tom bott2m bo1t2m

Amit Choudhary · Answer

hi friend yes you are right i found the bug. it was because of string.Replace funtion inside the insertSymbol function. well i have fixed it and now its working great. public static void InsertSymbol(string source int[] loc List Tokens) { string temp = ; for (int i = 0; i { temp = source; for(int j=0;j { string token = Tokens[i]; temp = temp.Remove(loc[j] 1); temp =temp.Insert(loc[j]-1 token[j].ToString()); } Output.Add(temp); } } Now please mark my answer.
