A number is a mathematical tool/aid used in counting and measuring.
We have been utilizing positive numbers for counting of index, such as
andNumber tool is easy to use to lable the address of home or lane numeber sequencily or telephone numbers, etc.
Nowadays, we use” index” in programming language to stack the data in order to use very effectively sorting the problems. So here also word “index” act as major role. If we take an array or string , we are always utilizing left to right counting/indexing such that
0,1,2,3,4,5,6,7,8……………………………n
That means we are indexing like increment numbers, which are very familiar from Kindergarten or Abacus or traditional counting games in village.
But there are few other options , why don’t be right to left instead of left to right. Yeah, it is pretty much adapted in “PYTHON-Programming Language”. Before that we had limitations and think lot to make reverse string printing, it is pretty boring( I felt, once I do)may be you were enjoying those stuff.
I don’t know exactly, are there any programing accept negative index in array indexing like python- programming language.…. If you know well. then comment on this
