codechef TAVISUAL - "the ball and cups" solution: http://ideone.com/rUl3RJ

#include <iostream>

#include <stdio.h>

using namespace std;

int main() {

int t, n, c, q, l, r, temp;

scanf("%d", &t);

while(t--) {

scanf("%d%d%d", &n, &c, &q);

for(int i=0; i<q; i++) {

scanf("%d%d", &l, &r);

if(c>=l && c<=r) {

temp=c-l;

c=r-temp;

}

}

printf("%d\n", c);

}

return 0;

}

note: place where cup stays(c), will change if only it falls between left and right changes(if(c>=l && c<=r)). after change cup's new position will be the the difference it had with left change before the change occurs(temp=c-l; c=r-temp;)
