Convert the following problem into a code fragment using an efficient nested if-else statement assume you a working a weather mapping coloring systems, and you are given a temperature variable that must be used to set a color variable (much like a test score and a letter grade). rules are:
rule 1: temperature0 then color-0
rule 2: 0 < temperature < 32 then color-2
rule 3: 32 < temperature-70 then color-3
rule 4: 70 < temperature < = 90 then colors 4
rule 3: 90 < temperature then color-5
