    i got through the sample test cases just with this code -_- i know its not the logic but i just used image explanation to formulate the idea.

    #include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

int main() {

    /* Enter your code here. Read input from STDIN. Print output to STDOUT */ 
    unsigned long n,a,b;
    unsigned long sum=0;
    scanf("%lu",&n);
    for(unsigned long i=0;i<n;i++)
    {
        scanf("%lu %lu",&a,&b);
  
        for(unsigned long j=a;j<=b;j++)
        {
            sum+=j;
        }
        printf("%lu",(sum-(b-a)));
    }
    return 0;
}
