bind values: integers = ints_range(1, 5, 1);
bind window = ints_window(values, 1, 3);
bind changed = ints_set(values, 0, 9);
var total: integer = 0;
repeat ints_len(window) as index {
total += window[index];
}
print(values, changed, window, total);
print(ints_to_vector(window), ints_join([integer: 6], [integer: 7]));
stdout
[integer: 1, 2, 3, 4, 5] [integer: 9, 2, 3, 4, 5] [integer: 2, 3, 4] 9
[2.0, 3.0, 4.0] [integer: 6, 7]
Write what you expect this program to print. Check prediction for a line-level hint without revealing the answer, or reveal the verified output when ready. This checks displayed text only; it does not run Scarp or save your input.
UNDERSTAND THE CODE
Explanation & practice
What this example teaches
Explicit integers values and integer window helpers
Expected behavior
Printed windows, replacements and totals
Practice: Read the source before looking at the output. Predict the values and their order, then use the pinned compiler to execute this lesson and compare the exact fixture. Identify which operation produces the result.
पूर्णांक कलेक्शन
integers पूर्णांकों का विशेष क्रम है। ints_range, ints_window, ints_set, ints_len, ints_to_vector तथा ints_join के साथ अलग-अलग गणनाएँ होती हैं। repeat से विंडो का योग निकाला गया है।
आउटपुट: values में 1–5, बदले हुए क्रम में पहला मान 9, और विंडो का योग 9 है।
अभ्यास: ints_set नया क्रम देता है या मूल बाइंडिंग को बदलता है?
Explanations are sourced from the project's English chapter guide and हिन्दी अध्याय. The Scarp program and output are unchanged.
SOURCE-BACKED SELF-CHECK · स्रोत-आधारित अभ्यास
Quick checkpoint / त्वरित अभ्यास
What total is produced by summing the integer window [2, 3, 4]?integer window [2, 3, 4] का योग कितना होता है?
Reveal the source-backed answer / सही उत्तर देखें
9 — ints_window selects 2, 3 and 4, and the repeat loop adds these three integers to obtain 9.9 — ints_window से 2, 3 और 4 चुने जाते हैं। repeat लूप इन्हें जोड़कर 9 प्राप्त करता है।
