solving problems on online judges

[zinayel]

I am a first year CS student, I learned C language very well and i was thinking about starting solving problems on online judges like UVa but i can't understand the questions and sample inputs and outputs, i haven't taken any algorithm courses at college though i have some small background, how can i start ?

I can give you example. Problem 11172.

Your program must read from standart input and write to standart output. (When you write input data in cmd (for example) and program writes results there).
Don't read and write to files.

This is code

Code: Select all

#include <stdio.h>

int main() {

  int a, b, t;

  scanf("%d", &t);

  while (t--) 
  {
    scanf("%d %d", &a, &b);

    if (a == b)  puts("=");
    if (a < b)   puts("<");
    if (a > b)   puts(">");
  }

  return 0;
}
