在给定的分子和分母范围内找到0..1之间给定随机实数的最接近整数分数

import random

def find_closest_fraction(N, M):
    x = random.random()
    min_diff = float('inf')
    closest_fraction = None

    for numerator in range(1, N+1):
        for denominator in range(1, M+1):
            fraction = numerator / denominator
            diff = abs(fraction - x)
            if diff < min_diff:
                min_diff = diff
                closest_fraction = (numerator, denominator)

    return closest_fraction

# 示例使用范围：分子范围1到10，分母范围1到10
closest_fraction = find_closest_fraction(10, 10)
print("最接近随机实数的分数是：", closest_fraction)
