Consider the following C program:
#include <stdio.h>
int gate (int n) {
int d, t, newnum, turn;
newnum = turn = 0; t=1;
while (n>=t) t *= 10;
t /=10;
while (t>0) {
d = n/t;
n = n%t;
t /= 10;
if (turn) newnum = 10*newnum + d;
turn = (turn + 1) % 2;
}
return newnum;
}
int main () {
printf ("%d", gate(14362));
return 0;
}The value printed by the given C program is _______ . (Answer in integer)

Show answer and explanation
Correct answer: 46
Explanation
The digits of 14362 are extracted from the left, and only those at odd positions (2nd and 4th) are appended to newnum. These digits are 4 and 6, so the result is 46.
