String Symbol Insertion Operation

A String Symbol Insertion Operation is a string edit operation that allows for the insertion of a symbol at some string position within a string.

• AKA: String Insertion Operation, Insert Item, StrSymIns.
• Context:
  • It is a fundamental operation in string editing and text processing.
  • It can be used to transform one string into another by adding characters.
  • It is commonly used in edit distance calculations and sequence alignment algorithms.
  • It can be performed at any valid position from 0 (before first character) to n (after last character) where n is the string length.
• Example(s):
  • StrSymIns('X',"ABCD",5) ⇒ "ABCDX" - inserting 'X' at the end.
  • StrSymIns('X',"ABCD",2) ⇒ "AXBCD" - inserting 'X' at position 2.
  • StrSymIns('Y',"ABCD",0) ⇒ "YABCD" - inserting 'Y' at the beginning.
  • DNA sequence editing where nucleotides are inserted into a sequence.
  • Text editor operations when typing new characters into existing text.
• Counter-Example(s):
  • a String Symbol Deletion Operation - removes rather than adds symbols.
  • a String Symbol Substitution Operation - replaces existing symbols rather than adding new ones.
  • a Graph Node Insertion Operation - operates on graph structures, not strings.
  • a Graph Edge Insertion Operation - operates on graph edges, not string symbols.
