##LongestWordInAnArticle.c LongestWordInAnArticle.c is a program which implement search a longest word in an article.

• Currently just support output last longest word
• word start with '-' or end with '-' will consider a word, so need to exclude them in the future
• Currently not support like 'What's'

$ gcc LongestWordInAnArticle.c LongestWordInAnArticle

$ ./LongestWordInAnArticle article1.txt

• Write Tests
• Add Code Comments

##SumOfN-thPowersIsAnN-thPower.c SumOfN-thPowersIsAnN-thPower.c is a program which implement Sum of n-th Powers Is an n-th Power:sum_of_powers_is_a_power.

• A^5 + B^5 + C^5 + D^5 + E^5 = F^5
• 0<A<=B<=C<=D<=E<=F<=75
• A^5 means power(A,5)

$ gcc SumOfN-thPowersIsAnN-thPower.c -lm -o SumOfN-thPowersIsAnN-thPower

$ ./SumOfN-thPowersIsAnN-thPower

##RecursionTwoDimensionalArray.c RecursionTwoDimensionalArray.c is a program which implement below algorithm:.

• Consider a N*N table , among it some cell is occupied, if two cells has at least one same edge, we think they are belong to a same group.
• You will find 3 groups with 2 cells(I marked it as 1 , 2 ,4), one group with 4 cells(3) and 2 group with only 1 cells (5,6)
• Suppose the table is combined with a two-dimensional arrays, write a function to calculate:
• Give you a cell in one group, please calculate the size of this group. For example , input: (1,3), output: 2
• Calculate the count of different groups. For this example: group1 is 2, group2 is 2, group 3 is 4, group4 is 2, group 5 is 1, group 6 is 1.
• List all groups.
• Design the test cases.
• For example , look at below table:
• 0 0 0 0 0 0 0 0 0 1
• 0 0 0 1 1 0 0 0 0 1
• 0 0 0 0 0 0 0 0 0 0
• 0 0 0 0 1 0 0 1 0 0
• 0 0 0 1 0 0 0 1 0 0
• 0 0 0 0 0 0 0 1 1 0
• 0 0 0 0 1 1 0 0 0 0
• 0 0 0 0 0 0 0 0 0 0
• 0 0 0 0 0 0 0 0 0 0
• 0 0 0 0 0 0 0 0 0 0
