Using the top row of letters on a computer keyboard, only 1 country can be spelt out. What is the country?

A QWERTY (pronounced KWEHR-tee) keyboard is named after the first six letters of the keyboard's grid. Originally used in typewriter design, the layout of the numbers was devised to reduce the jamming of type bars which moved toward the paper for each letter typed. Fast typists could press a new key and the type bar of that key, on rising, jam with the type bar of the previous key's type bar as it fell back into position. In some countries, such as France, the equivalent keyboard is known as an AZERTY keyboard, with the Q and W keys swapped with the A and Z key respectively. The full keyboard letter set is QWERTYUIOP or AZERTYUIOP and the letters PERU can be typed from either version of the keyboard.
