Question

There are an array given if i would add one number in the last index then second array element should be change

_array = [7,9,9];
j=0;
stringLength = 0;
addition = 1;

for (let i=_array.length-1;i>=0;i--){
 
 //  if(j == 0){
       tmp = _array[i]+addition;
       stringIndex = tmp.toString().split('');
       stringLength = stringIndex.length;
       
 // }
   
   if(stringLength == 2){
       addition = parseInt(stringIndex[0]);
       _array[i] = parseInt(stringIndex[1]);
   }
   else{
      _array[i] = tmp;
       addition=0;
   }
    j++;
}
