Python Algorithm Basics

1. Two-D array 90-degree rotation

data = [[col for Col in Range (4)] for row in range (4)]for v in Data:print (v) for R_index,row in Enumerate (data): for        C_index in range (R_index,len (ROW)): TMP = Data[c_index][r_index] data[c_index][r_index] = Row[c_index] Data[r_index][c_index] =tmpfor v in Data:print (v)

2. Two points Search

Def binary_search (data_source,find_n):     mid = int (len (data_source)/2)     if len (data_source)  >= 1:         if data_source[mid] > find_n:             binary_search (data_source[:mid],find_n)         elif  data_source[mid] < find_n:             binary_search (data_source[mid:],find_n)         else:             print ("Find")     else:         print ("Cannot find") if __name__ ==  ' __main __ ':     data = list (Range (1, 6000, 3))     print ( Data)      Binary_search (data,30)
