To solve the problem, we need to count the number of 1s in the given block of text.

Approach:

1. Observe the structure of the input: Each line contains 10 1s separated by spaces.
2. Count the number of lines: There are 100 lines in total.
3. Calculate the total number of 1s: Multiply the number of 1s per line (10) by the number of lines (100).

Result:

10 × 100 = 1000

Answer: 1000
