Given an array of strings and an array of ints, associate them from longest to shortest according to the length of each string. The output format must be a string with the syntax:
name1:number1,name2:number2,name3:number3... nameN:numberN
Input example:
String[]names = {"Ana", "Miguel", "Josemanuel"} int[]numbers = {1034, 21, 537}
Output example:
"JoseManuel:1034,Miguel:537,Ana:21"
