1054. The Dominant Color (20)

题目

Behind the scenes in the computer’s memory, color is always talked about as a series of 24 bits of information for each pixel. In an image, the color with the largest proportional area is called the dominant color. A strictly dominant color takes more than half of the total area. Now given an image of resolution M by N (for example, 800x600), you are supposed to point out the strictly dominant color.

Input Specification:

Each input file contains one test case. For each case, the first line contains 2 positive numbers: M (<=800) and N (<=600) which are the resolutions of the image. Then N lines follow, each contains M digital colors in the range [0, 224). It is guaranteed that the strictly dominant color exists for each input image. All the numbers in a line are separated by a space.

Output Specification:

For each test case, simply print the dominant color in a line.

Sample Input:
5 3
0 0 255 16777215 24
24 24 0 0 24
24 0 24 24 24
Sample Output:
24

解答

用了字典来统计各个数字出现的次数。

li=[int(x) for x in input().split(' ')]
M=li[0]
N=li[1]
dic={}
max=0
maxc=None
for i in range(N):
    li = input().split(' ')
    for c in li:
        if c in dic:
            dic[c]+=1
            if max< dic[c]:
                max=dic[c]
                maxc=c
        else:
            dic[c]=1
            if max< dic[c]:
                max=dic[c]
                maxc=c
print (maxc)
