查找非零的索引并计算出现之间的间隔

def find_nonzero_indices(arr):
    nonzero_indices = []
    for i in range(len(arr)):
        if arr[i] != 0:
            nonzero_indices.append(i)
    return nonzero_indices

def calculate_intervals(nonzero_indices):
    intervals = []
    for i in range(1, len(nonzero_indices)):
        interval = nonzero_indices[i] - nonzero_indices[i-1]
        intervals.append(interval)
    return intervals

# 示例输入
arr = [0, 1, 0, 0, 2, 0, 3, 4, 0, 5, 0]

# 查找非零索引
nonzero_indices = find_nonzero_indices(arr)
print("非零索引：", nonzero_indices)

# 计算间隔
intervals = calculate_intervals(nonzero_indices)
print("间隔：", intervals)

非零索引： [1, 4, 6, 7, 9]
间隔： [3, 2, 1, 2]
