    {#blank#}2{#/blank#} She had been invited to help program a new computer, the job of which was to quickly deal with the math problems ships used to find their way.{#blank#}3{#/blank#} Then it translated the patterns of holes into the math problems it was supposed to solve.

    One afternoon in 1947 Hopper and her team were running a program.

The moth was blocking some of the holes in the paper—{#blank#}5{#/blank#} Some people think Hopper was the first person to use the word “debug” to mean “get rid of the problems in a computer”.
