The project runs in Python3+ environment with Tkinter for GUI. It's best to use with Linux OS.

Dictionary store count of words

• constant time O(1) access, given key

List store array results(like- words, lines)

• Easy to store/handle elements and perform linear search

• Highlight keywords in lines shown in GUI

• remove punctuations(like- ?, !)

• for string processing

• to render GUI

• to show graph

• Most functions use linear search over space(words, lines) so increasing file size increases computation time
• File with many words may not fit in the limited space of graph reserved in GUI - user has to use toolkit provided with zooming options

• mostoccuringWord - calculate hashMap/dictionary for words and maximumOccurence of any word, then does linear search over dictionary to find keys corresponding to value(=maximumOccurence)
• leastOccuringWord - call wordMapper(function), find minimum value in hashmap/dictionary and then find keys with this value by linear search over dictionary
• lineCounter - call removeEmptyLines(function) and then count lines
• wordCounter - call wordMapper(function) and find number of keys(=words) in hashMap/dictionary by it's size

• Implementation is case insensitive
