Computer Science History

Some Notable Influential Computer Scientists

Charles Babbage (1791–1871)— Invented the Mechanical Computer
Alan Turing (1912–1954) Credited as the first Computer Scientist
Edsger Dijkstra (1930–2002) Created the Shortest Path Algorithm
Grace Hopper (1906–1992) Created the Compiler

Popular Computer Science Algorithms

Sorting algorithms

Bubble Sort

1 for i = 1 to A.length - 1
2 for j = A.length downto i + 1
3 if A[j] < A[j - 1]
4 exchange A[j] with A[j - 1]

Selection Sort

Merge Sort

Search Algorithms

Binary Search

binary_search(A, target):
lo = 1, hi = size(A)
while lo <= hi:
mid = lo + (hi-lo)/2
if A[mid] == target:
return mid
else if A[mid] < target:
lo = mid+1
hi = mid-1

// target was not found
