给定范围内数组的两个元素之间的最大差值

def find_max_difference(arr, start, end):
    # 找到给定范围内的最小值和最大值
    min_val = float('inf')
    max_val = float('-inf')
    for i in range(start, end+1):
        if arr[i] < min_val:
            min_val = arr[i]
        if arr[i] > max_val:
            max_val = arr[i]
    
    # 计算最大差值
    max_diff = max_val - min_val
    
    return max_diff
