Question

So, In a string containing multiple 1\'s,

Now, it is possible that, the number

\'1\' 

appears at several positions, let\'s say, at m

Answer 1

Perhaps the following route will help:

1. Convert string to a vector of integers characters

   v <- as.integer(strsplit(s, "")[[1]])
   

2. Repeatedly convert this vector to matrices of varying number of rows...

   m <- matrix(v, nrow=...)
   

3. ...and use rle to find relevant patterns in the rows of the matrix m:

   rle(m[1, ]); rle(m[2, ]); ...
