186 views

Assumption:

  • The input strings will contain only numeric digits
  • The input strings can be of any large lengths
  • The lengths of the two input string need not be the same
  • The input strings will represent only positive numbers

Example

If input strings are “1234” and “56”, the output string should be “1290”
If input strings are “56” and “1234”, the output string should be “1290”
If input strings are “123456732128989543219” and “987612673489652”, the output string should be “123457719741663032871”

 public addition(){
  String max=input1.length()>input2.length()?input1:input2;
  String min=input1.length()
  int a,b,add;
  int carry=0;
  String output="";
  int minLen=min.length()-1;
  int maxLen=max.length()-1;
  while(minLen>-1){
  a=Integer.parseInt(max.charAt(maxLen--)+"");
  b=Integer.parseInt(min.charAt(minLen--)+"");
  add=a+b+carry;
  carry=0;
  if(add>9){
  carry=1;
  add=add%10;
  }
  output=add+output;
  System.out.println(output);
  }
  max=input1.substring(0,input1.length()-input2.length());
  add=Integer.parseInt(max);
  add+=carry;
  return add+""+output;
}

Weight of vowels that appear in the string should be ignored and All non-alphabetic characters in the string should be ignored.

Weight of each letter is its position in the English alphabet system, i.e. weight of a=1, weight of b=2, weight of c=3, weight of d=4, and so on….weight of y=25, weight of z=26
Weight of Upper-Case and Lower-Case letters should be taken as the same, i.e. weight of A=a=1, weight of B=b=2, weight of C=c=3, and so on…weight of Z=z=26.

Example1:
Let us assume the word is “Hello World!!”
Weight of “Hello World!!” = 8+0+12+12+0+0+23+0+18+12+4+0+0 = 89
Note that weight of vowels is ignored. Also note that the weight of non-alphabetic characters such as space character and ! is taken as zero.
