Why does using cin cout instead of scanf and printf gives tle for the question : MULTQ3 Problem - CodeChef ?
My code using printf and scanf : CodeChef: Practical coding for everyone
This got AC in time 0.11
My code using cin and cout : CodeChef: Practical coding for everyone
This got TLE. Should we not use cin and cout?
cin and cout run at about 3 times slower than scanf and printf and therefore chances of TLE are high for large inputs.
let us consider it is 8 times slow. my solution got AC for time 0.11 s. Then the time for 8 time slow input should be 0.88 s. Time limit is 1 s.
does your code contain only cin and cout? no. therefore you cannot just say 0.11*8. it doesnt work that way.
