Linear Regression is the predicting the value of one scalar variable(y) using the explanatory another variable(x). Linear regression is represented by the equation Y = a + bX, where X is the explanatory variable and Y is the scalar variable. The slope of the line is b, and a is the intercept. For linear list …
Radix Sort is a non-comparison sorting algorithm — it never compares two elements directly. Instead, it sorts by processing individual digits, one digit position at a time from least significant to most significant (LSD approach). This lets it sort integers in O(n) time for a fixed number of digits, breaking the O(n log n) lower …
Exercise 1-19. Write a function reverse(s) that reverses the character string s. Use it to write a program that reverses its input a line at a time. Approach The core algorithm is the classic two-pointer swap: place one index at the start of the string (i = 0) and one at the end (j = …
Exercise 1-18. Write a program to remove trailing blanks and tabs from each line of input, and delete entirely blank lines. The challenge here is that you cannot know whether a blank or tab is “trailing” until you have seen everything that follows it on the same line. The solution splits the work into two …
Interpolation search is an algorithm used for searching a given value in an ordered indexed array. Interpolation search is sometimes called as extrapolation search. For uni formally distributed data items Interpolation search is the best method. for example: library books directory. Read more about C Programming Language. /************************************************************ You can use all the programs on …
Exercise 1-17. Write a program to print all input lines that are longer than 80 characters. Approach This exercise is a direct application of the getline / main pattern introduced in K&R Section 1.9 — but now with a filter condition added to main. The key insight is that getline already returns the line length, …
