15. Write a program to generate a sequence 0,1,1,2,4,7,13,24,44,... using an array

16. Write a program to accept a set of numbers and identify the coprimes within that set. Coprimes are those numbers which have GCD = 1

17. Write a program to perform binary searching in a set of numbers

18. Write a program to add two polynomials. The coefficients are stored in separate arrays

19. Write a program to accept the output values for a logic function F(x,y,z). Identify the function from those output values

20. Write a program to accept a set of numbers. Then read a number and print the subsets which have a sum equal to this number

21. Write a program to accept a set of numbers and reverse the order

22. Write a program to subtract two polynomials. The coefficients are stored in separate arrays

23. Write a program to accept a set of numbers. Then read a number and print the subsets which have a product equal to this number

24. Write a program to print the second largest number among a set of numbers

25. Write a program to compute the fibonacci series using an array

26. Write a program to add two matrices

27. Write a program to sort the values in a matrix row-wise

28. Write a program to print the row sums and column sums of a matrix

29. Write a program to sort the values in a matrix in row-major form

30. Write a program to multiply two matrices

31. Consider a system for a Vigenere cipher system. The system consists of a matrix which is filled with a set of predefined values (even though it is normally considered for strings, we take it for numbers). The matrix is filled like:
    0 1 2 3 4 5 6 7 8 9
    1 2 3 4 5 6 7 8 9 0
    2 3 4 5 6 7 8 9 0 1
    3 4 5 6 7 8 9 0 1 2
    4 5 6 7 8 9 0 1 2 3
    5 6 7 8 9 0 1 2 3 4
    6 7 8 9 0 1 2 3 4 5
    7 8 9 0 1 2 3 4 5 6
    8 9 0 1 2 3 4 5 6 7
    9 0 1 2 3 4 5 6 7 8
    Enter a number. Then take adjacent digits and lookup the table with 1st digit forming the row number and 2nd digit forming the column number. Then display the digit at that location. Repeat it for the rest of the number."

32. Write a program to convert a matrix to a sparse matrix. A sparse matrix is a special notation where only non-zero values of the matrix are represented using the notation <row number , column number , value>

33. Write a program to sort the values in a matrix column-wise

34. Write a program to sort the values in a matrix in column-major form

35. Write a program to find the transpose of a matrix

36. Write a program to print the largest row sum and column sum in a matrix

39. Write a program to sort a set of strings using bubble sort

40. Write a program to compare two strings irrespective of the case without using any library function

41. Write a program to count the number of words in a string without using any library function

42. Write a program to reverse the odd words in a string without using any library function

43. Write a program to replace the occurrence of 'the' with 'a' in a string without using any library function. Replacement should occur even if 'the' occurs within a word

53. Write a program to implement any sorting system recursively

54. Write a function implementation to reverse a string without using any library function

55. Write a program to implement a sorting system for numbers using functions

56. "Write a user-defined function that finds the square root of a number without using any library function. The square root can be found out like below. Consider 40. 36<40<49 So, square root lies between 6 and 7. Take the average. You get 6.5. The square is 42.25. So, the square root lies between 6 and 6.5. Again take average to get 6.25. The process repeats. Continue for a maximum of 6 iterations."56.

57. "Write a program using macros to find the kernel value in the sine series expansion. The kernel value is defined as f(x,n)=(-1)^(n+1) x*n/n!
