How do you find out how many times does the number 5 appear on a digital clock in 24 hours?
To determine how many times the number 5 appears on a digital clock in 24 hours, you can analyze each digit position (hours and minutes). The hours range from 00 to 23, where '5' appears once in the hour (05 and 15). For the minutes, '5' appears in every ten-minute interval (05, 15, 25, 35, 45, 55) for each hour, totaling 6 occurrences per hour. Combining these, '5' appears 2 times in the hour and 6 times in minutes for 24 hours, resulting in a total of 2 (from hours) + 6 x 24 (from minutes) = 146 occurrences.
What is the program to figure out how many numbers from 0 to 9 are needed for 1 to 89 for example?
#include<iostream> #include<array> #include<sstream> std::array<int,10> get_frequency (int range_min, int range_max) { if (range_max<range_min) std::swap (range_min, range_max); std::array<int,10> digit {}; for (int count {range_min}; count<=range_max; ++count) { std::stringstream ss {}; ss << count; std::string s {}; ss >> s; for (auto c : s) { ++digit[c-'0']; } } return digit; } int main () { std::array<int,10> digit {}; digit = get_frequency(1, 89); std::cout << "In the range 1 to 89...\n"; for (int d {0}; d<10; ++d) { std::cout << "\tthe digit " << d << " appears " << digit[d] << " times.\n"; } } Output: In the range 1 to 89... the digit 0 appears 8 times. the digit 1 appears 19 times. the digit 2 appears 19 times. the digit 3 appears 19 times. the digit 4 appears 19 times. the digit 5 appears 19 times. the digit 6 appears 19 times. the digit 7 appears 19 times. the digit 8 appears 19 times. the digit 9 appears 9 times.

How many times will the digit 7 appear on a 24 hour digital clock?
158 In every hour of the day except 7 am and 7 pm the digit 7 appears on the clock 6 times. you take 2 hours (7am and 7pm) out of 24 hours and the rest are 22 hours. Then 22 hours multiply x 6 because in each of the 22 hours 7 appears 6 times, 22 x 6 makes 132. The remaining 2 hours from 24 are 7am and 7pm, 7 appears 13 times in each of these hours; 7:00, 7:07, 7:17, 7:27, 7:37, 7:47, 7:57. Then you do 13 x 2 because there are 2 7:00 (am and pm), you get 26. Now the total of 132 from 22 hours and 26 from the other 2 hours brings the total of 158; 132+26=158, our final answer is 158. so in 24 hours the digit 7 appears in 158 different times on a digital clock.

How many times does the number 5 appear on a 24 hour digital clock answer?
The number 5 appears 12 times on a 24-hour digital clock. It appears once in the hour (05:00, 15:00) and once in the minutes for each hour from 00 to 23 (e.g., 00:05, 01:05, ..., 23:55), resulting in 10 occurrences in the minutes. Therefore, the total is 2 (from the hours) + 10 (from the minutes) = 12.
