# Python: List of integers where the sum of the first i integers is i

## Python Programming Puzzles: Exercise-7 with Solution

Write a Python program to check a given list of integers where the sum of the first i integers is i.

Input: [0, 1, 2, 3, 4, 5] Output: False Input: [1, 1, 1, 1, 1, 1] Output: True Input: [2, 2, 2, 2, 2] Output: False

**Sample Solution:**

**Python Code:**

```
def test(li, i):
return sum(li[:i]) == i
nums = [0,1,2,3,4,5]
i = 1
print("Original list:")
print(nums)
print("Check the said list, where the sum of the first i integers is i: i = ",i)
print(test(nums,1))
i = 3
print("\nOriginal list:")
print(nums)
print("Check the said list, where the sum of the first i integers is i: i = ",i)
print(test(nums,3))
i = 6
nums = [1,1,1,1,1,1]
print("\nOriginal list:")
print(nums)
print("Check the said list, where the sum of the first i integers is i: i = ",i)
print(test(nums, 6))
i = 2
nums = [2,2,2,2,2]
print("\nOriginal list:")
print(nums)
print("Check the said list, where the sum of the first i integers is i: i = ",i)
print(test(nums, 2))
```

Sample Output:

Original list: [0, 1, 2, 3, 4, 5] Check the said list, where the sum of the first i integers is i: i = 1 False Original list: [0, 1, 2, 3, 4, 5] Check the said list, where the sum of the first i integers is i: i = 3 True Original list: [1, 1, 1, 1, 1, 1] Check the said list, where the sum of the first i integers is i: i = 6 True Original list: [2, 2, 2, 2, 2] Check the said list, where the sum of the first i integers is i: i = 2 False
