  • There are two gates. One goes to hell and the other goes to heaven. The
    gatekeeper asks a puzzle to Sahil in order to decide which gate he
    should open for him. Obviously if Sahil answers the puzzle correct , the
    gate to heaven will be opened else the gate to hell. According to the
    problem Sahil is given n consecutive integers from 1 to n ,which are
    written in a row. He has to put signs “+” and “-” in front of them so
    that the expression obtained is equal to 0 or, if the task is impossible
    to do,then Sahil should tell the gatekeeper “No solution exists for the
    given problem “.The gatekeeper expects Sahil to find his answer in
    minimum time using an efficient approach rather than examining all
    possible ways to place the signs. Sahil comes to you considering you as
    his friend. Would you help him out to get to the solution ?
