将前缀添加到数组的特定值

def add_prefix_to_value(arr, value, prefix):
    for i in range(len(arr)):
        if arr[i] == value:
            arr[i] = prefix + value
    return arr

# 示例用法
my_array = ["apple", "banana", "orange", "banana"]
specific_value = "banana"
prefix = "fruit_"

result = add_prefix_to_value(my_array, specific_value, prefix)
print(result)
