hey @Chirag-Jain-1414278322030453 your conversion from string to integer is wrong, instead of num = num + ((test[len-1-k])*pow(10,k));, num = num + ((test[len-1-k] - ‘0’)*pow(10,k)); would come. Other than that it is mentioned in question that each character/digit can be used only once and your approach is wrong in that case.
