在字符串的每个单词的末尾插入字符串

def insert_string_at_end_of_each_word(input_string, insert_string):
    # Step 1: Split the input string into word array
    words = input_string.split()

    # Step 2: Iterate over each word and insert the string at the end
    for i in range(len(words)):
        words[i] += insert_string

    # Step 3: Rebuild the string by joining the modified word array
    output_string = ' '.join(words)

    return output_string

# Example usage
input_string = "This is a sample string"
insert_string = "insert"
output_string = insert_string_at_end_of_each_word(input_string, insert_string)
print(output_string)
