In computer science, An "Interval Tree" is an ordered tree data structure to hold intervals. Specifically, it allow one to efficiently find all intervals that overlap with any given interval

Finding Last Occurrence of Word in String
Logic to Search 'Last Occurrence' of a word is almost similar to searching first occurrence of a word in string. Just with last occurrence of a word do not terminate loop if first occurrence

C Finds a Year is Leap or not is a bit Tricky
C Program Code we generally assume that if a year number is evenly divisible by 4 is leap year. But it is not the only case. A year is a leap year if it is evenly divisible by 100. If it is
